How to Operate and Use a Synchronized Chip Seal Asphalt Truck

Asphalt spreader is used to spread the penetration oil, waterproof layer and bonding layer of the bottom layer of asphalt pavement of high-grade highway. It can also be used for the construction of county and township highway oil roads with layered paving technology. It consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform.
Knowing how to properly operate and maintain the asphalt spreader can not only extend the service life of the equipment, but also enable the construction project to proceed smoothly. So what problems should the asphalt spreader pay attention to when working? The technicians of Gaoyuan Road Construction Machinery Equipment Co., Ltd. give you tips:
1). Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreader, check the four thermal oil valves and the pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Test the asphalt pump and circulate for 5 minutes. If the pump head shell is hot, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not turn or make noise. In this case, the valve needs to be opened to continue heating the asphalt pump until it can operate normally. During the working process, the asphalt liquid must be kept at a working temperature of 160~180℃, and it cannot be filled too full (pay attention to the liquid level pointer during the injection of asphalt liquid, and check the tank mouth at any time). After the asphalt liquid is injected, the filling port must be closed tightly to prevent the asphalt liquid from overflowing during transportation.
2). During use, asphalt may not be pumped in. At this time, it is necessary to check whether the interface of the asphalt suction pipe is leaking. When the asphalt pump and pipeline are blocked by solidified asphalt, a blowtorch can be used for baking, and the pump must not be forced to turn. When baking, care should be taken to avoid directly baking the ball valve and rubber parts.
3). When spraying asphalt, the car should be driven at a low speed. Do not step on the accelerator hard, otherwise it may cause damage to the clutch, asphalt pump and other components. If 6m wide asphalt is spread, pay attention to obstacles on both sides at any time to prevent collision with the spreading pipe. At the same time, the asphalt should be kept in a large circulation state until the spreading work is completed. After the work is completed every day, if there is any remaining asphalt, it must be returned to the asphalt pool, otherwise it will solidify in the tank and cannot work next time.
4). In addition, the emulsifier must also pay attention to daily maintenance:
1. The emulsifier and delivery pump and other motors, agitators, and valves should be maintained daily.
2. The emulsifier should be cleaned after work every day.
3. The speed regulating pump used to control the flow should be regularly tested for accuracy, and adjusted and maintained in time. The asphalt emulsifier should regularly check the matching clearance between its stator and rotor. When the minimum clearance specified by the machine cannot be reached, the stator and rotor should be replaced.
4. If the equipment is out of use for a long time, the liquid in the tank and pipeline should be emptied (the emulsifier aqueous solution should not be stored for a long time), the hole covers should be tightly closed, kept clean, and the running parts should be filled with lubricating oil. When it is used for the first time or when it is used again after a long period of inactivity, the rust in the tank should be removed, and the water filter should be cleaned regularly.
5. Regularly check whether the terminal in the electric control cabinet is loose, whether the wires are worn during shipment, and remove dust to avoid damage to the machine parts. The frequency converter is a precision instrument. Please refer to the instruction manual for specific use and maintenance.
6. There is a heat transfer oil coil in the emulsifier water solution heating stirring tank. When injecting cold water into the water tank, the heat transfer oil switch should be turned off first, and then the switch should be turned on to heat after adding the required amount of water. Pouring cold water directly into the high-temperature heat transfer oil pipeline can easily cause the weld to crack.

1. There are generally three ways to heat emulsified bitumen plant: gas heating, heat transfer oil heating and open flame heating. The first is the gas heating method of emulsified bitumen plant. The gas heating method of emulsified bitumen plant requires the use of the fire pipe to transport the high-temperature smoke generated by high-temperature combustion through the fire pipe.
2. The heat transfer oil heating method of emulsified bitumen plant mainly uses heat transfer oil as a medium for heating. The heat transfer oil heating method has extremely high requirements for fuel. The fuel must be fully burned and the product must be transferred to the heat transfer oil after sufficient heat is transferred to the heat transfer oil pump for heating.
3. The open flame heating method of emulsified bitumen plant is the most direct and convenient heating method. Whether in terms of convenient transportation or coal consumption, the open flame heating method is the fastest choice, simple operation, sufficient fuel, structural design, and labor intensity are relatively reasonable.

The slurry sealer is a special equipment for road maintenance that we see in our lives. The slurry sealer is mainly used to deal with the decrease in surface wear resistance, cracks, etc. of the road, to improve the waterproofness and skid resistance of the road surface, thereby greatly improving the driving comfort and flatness inside, so as to achieve a new effect for the road surface. So what is the operation process of the slurry sealer?
Before starting the slurry sealer, you should be prepared to test the quality of the slurry sealer materials before construction. One of the most important points is to certify and inspect whether the content of emulsified asphalt can meet the requirements of the specification, and the mixture should also meet the requirements. After confirming the measurement standards, check that the road surface to be constructed should be dry, free of debris, water, flat, etc.

The difficulty of emulsified bitumen equipment itself, because general bitumen also has different classifications, in the production and processing of emulsified bitumen equipment bitumen concrete, it is necessary to pay attention to whether the common raw materials are the common bitumen and ensure the quality. Check the black antistatic tweezers of emulsified bitumen equipment asphalt concrete machine equipment emulsified bitumen equipment.
If the gap of the black antistatic medical tweezers bitumen concrete micro-powder machine of emulsified bitumen equipment is enlarged after long-term use, then we can adjust it and continue to process it. Emulsified bitumen equipment is a relatively simple difficulty.

Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreading truck, check the four thermal oil valves and air pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Try running the asphalt pump and cycle for 5 minutes. If the pump head shell is hot to your hands, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not rotate or make noise. You need to open the valve and continue to heat the asphalt pump until it can operate normally.

as key equipment in road maintenance, possess comprehensive functions including cooling, dust removal, washing, and emergency response. Their technological value is reflected in the following dimensions:
I. Road Protection: Cooling and Structural Maintenance Utilizing a front-flush device (92 m3/h flow rate) and a 30-meter range water cannon in tandem, maintaining a travel speed of 25 m/min and a spraying interval of 90 minutes. The Zhengzhou case shows that during high-temperature periods, the road surface temperature decreased by 11℃, rut depth decreased by 38%, and the lateral temperature difference monitored by infrared sensors was ≤±2℃.
II. Air Purification: Dust Suppression and PM2.5 Control An external mixing self-priming pump (≤7-meter self-priming height) combined with a 45° upward-angle side spray maintains a stable water pressure of 0.8-1.2 MPa. By switching the droplet size (120μm/80μm) at different times, PM10 concentration is reduced by 42 μg/m3, and respirable dust is reduced by 38%. III. High-Pressure Washing: Rainwater and Sewage Co-operation

Asphalt mixture is a kind of composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, some also added polymer and wood cellulose; By these different quality and quantity of materials mixed to form different structures, and have different mechanical properties

No matter what product is used, after using it for a period of time, some large and small problems will inevitably arise, which will affect our work, just like the use of asphalt heating equipment will cause problems such as uneven asphalt pavement. We know that for the use of asphalt heating equipment, the construction of asphalt pavement is affected by many factors, including the quality of construction personnel, the quality of roadbed construction, the treatment of the two sections of the bridgehead culvert and the expansion joint of the bridge, the construction of the road subbase and base, the selection of road construction machinery and the quality of road materials. These are the main reasons affecting the flatness of the road surface.
In order to better help customers apply it, professionals introduce the use of asphalt heating equipment. Flatness is an important indicator for measuring the quality of high-grade pavement. Unsmooth pavement will increase driving resistance and cause additional vibrations in the vehicle, which will directly affect the safety and comfort of driving. At the same time, it will aggravate the damage of automobile parts and tires and increase fuel consumption.

Emulsified asphalt is a special asphalt product with many unique properties and advantages. Here are some of its main characteristics:
High fluidity and good wetting properties:
Emulsified asphalt has excellent fluidity and strong wetting properties. This allows for precise control of the application rate during tack coat, primer coat, layering, and spraying, resulting in good penetration and adhesion.
The asphalt content of emulsified asphalt can be adjusted arbitrarily, up to 67%, resulting in more uniform mixing and a thinner asphalt film. Furthermore, due to the surface charge of emulsified asphalt, asphalt particles can tightly adhere to the aggregate surface, and the emulsifier also acts as an anti-stripping agent, enhancing the bond between asphalt and aggregate.
Expanded application range:
With the continuous development of emulsified asphalt technology, many functions that hot asphalt cannot achieve can be accomplished with emulsified asphalt. This greatly expands the application range of emulsified asphalt. Energy Saving and Environmentally Friendly: Emulsified asphalt requires only one heating step during production, and the asphalt temperature is only 120-140℃, which is much lower than the heating temperature of hot asphalt. Although the emulsifier solution requires heating and the emulsification machinery consumes electricity, statistical calculations show that using emulsified asphalt for road construction and maintenance can save more than 50% of heat energy compared to using hot asphalt. Furthermore, the production and construction process of emulsified asphalt avoids prolonged high-temperature heating, reducing environmental pollution and burn accidents.

The bitumen (composition: asphaltene and resin) drum melting machine adopts a self-heating integrated structure, which integrates the thermal oil boiler used in the old asphalt drum melting machine and the barrel removal equipment itself, reducing the volume of the entire equipment and significantly It reduces equipment investment (actual significance: it is the accumulation of future profits), saves the space occupied by the equipment and the logistics cost of switching sites. The combustion chamber is placed inside the equipment itself, which greatly reduces thermal damage and improves heat utilization.

I. Essential Attributes from a Functional Perspective
Asphalt distributor trucks are typical special-purpose engineering vehicles, their core function being the precise spraying of high-temperature asphalt. Equipped with specialized equipment such as asphalt tanks, heating systems, and spraying devices, they are designed specifically for road construction scenarios. This deep customization for a single operational scenario fundamentally differs from the multi-purpose transportation positioning of ordinary trucks.
II. Usage Scenarios Determine Classification
These vehicles only appear in specific situations: construction sites for new road paving, old road renovation, etc. Their working mode is fixed-point operation rather than long-distance transportation, with an average speed typically not exceeding 20 kilometers per hour. This limited usage scenario contrasts sharply with the cross-regional mobility of trucks, better aligning with the definition logic of a special-purpose vehicle.
III. Special Structural Design
Observing their physical characteristics reveals clues: the complete isolation between the cab and the work area ensures construction safety; the hydraulic control system achieves spraying precision; some models also have a stone chip spreading function. These designs optimized for a single operation make their overall structural complexity far exceed that of ordinary trucks, further confirming their special-purpose vehicle attributes.

I. The Impact of Temperature on Asphalt Laying
Temperature is a crucial parameter in asphalt laying. Generally, the laying temperature should be between 5-35 degrees Celsius to ensure surface quality. If the temperature is too low, the following problems will occur:
1. Asphalt will not flow easily. At low temperatures, the asphalt will solidify and become difficult to flow, affecting the uniformity of the laying process.
2. Reduced construction quality. The asphalt surface will be rough, leading to cracks and potholes, which will affect road use.
3. Increased waste. Lower temperatures increase the hardness of the asphalt, making construction more difficult, increasing the amount of asphalt needed, and raising construction costs.
II. How low is “too low”?
So, how cold is considered “too cold”? Actually, the specific value for “too low” depends on different situations. Generally, the following are some common situations:
1. The temperature of the asphalt mixture should be between 120-165 degrees Celsius. If the temperature is below this range, the fluidity of the mixture will decrease, increasing the difficulty of construction.
2. The construction temperature for asphalt pavement should be between 10-30 degrees Celsius. If the temperature is below this range, the asphalt will harden, making it difficult to lay properly and easily causing pavement cracking.
Therefore, the specific temperature will vary depending on the specific asphalt paving situation. If you need to pave asphalt, please consult a professional construction company in advance and understand the local temperature conditions.

Bitumen emulsion equipment is widely used in new technologies and new processes for preventive maintenance. Bitumen emulsion plant is an emulsion at room temperature formed by dispersing bitumen into the water phase. It is a new material that is made of natural materials. It is different from traditional Compared with hot bitumen, it saves more than 50% of energy, saves 10%-20% of bitumen, and causes less pollution.

Synchronous gravel sealer fog sealer is a method of road maintenance. Some roads have network cracks, cracks and holes after a few years of use. The effective method is fog seal technology. The cost is very low. After the fog seal, due to the large fluidity of the material, it can penetrate into the aggregate and flow into the cracks to “transfuse” the road surface, restore the asphalt adhesion of the road surface, fill small cracks and gaps, prevent water from penetrating the road surface, and keep the road surface performance for 2 to 3 years, delaying the high maintenance cost and improving the economic benefits.

Sand-containing mist seal is a common anti-corrosion coating. Its construction process is relatively simple, but the following points should still be noted:
Surface treatment: Before construction, the surface to be coated needs to be cleaned and all grease, dirt, rust and old coatings need to be removed.
Mixed materials: Mix the polyurethane resin and pigment in a certain proportion to ensure the quality of the coating.
Construction tools: Usually a spray gun or sprayer is used for construction. Before construction, the state and pressure of the nozzle should be checked to see if they are normal.
Spraying direction: Pay attention to the spraying direction during construction, and try to make the particles perpendicular to the surface.
Protection time: After construction, protection should be carried out for the prescribed time to avoid damage to the coating due to external forces.
In general, the construction of sand-containing mist seal is relatively simple, but attention should still be paid to details and quality control. Reasonable construction methods and precautions can ensure the quality and service life of the coating.

Asphalt distributor is a kind of black road construction machinery. It is the main equipment for highway, urban road, airport and port wharf construction. The equipment is mainly used for spraying different kinds of bituminous pavement to meet the construction requirements of different grades of pavement penetration layer, sticky layer, up and down seal layer, fog seal layer and so on.
However, the effect of some asphalt sprinkles on the market is not satisfactory, and there will be a phenomenon of uneven distribution of the transverse distribution. At this time, a certain measure is adopted to effectively improve the transverse uniformity of asphalt spreading.

Water is one of the raw materials of the modified asphalt storage tank, and it is distributed in various components of the modified asphalt storage tank equipment. According to the components where water is distributed, the anti-cold measures are explained one by one. The water tank of the modified asphalt storage tank, the water inside the water tank is released through the filter valve. Some instruments of the modified asphalt storage tank do not have a filter valve to save the cost of the equipment. The modified asphalt storage tank can only be drained by loosening the flange bolts at the bottom. The water pump of the modified asphalt storage tank mentioned here includes a hot water pump and a circulating water pump. This type of water pump for the modified asphalt storage tank generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. The modified asphalt storage tank pays attention to the sewage treatment of the sewage outlet at the bottom of the pump. The modified asphalt storage tank emulsion tank generally uses a cone bottom. However, in order to better process the modified asphalt storage tank coefficient, the inlet and outlet are usually not placed at the bottom of the modified asphalt storage tank. Emulsion (mostly water) will remain at the bottom of the tank, and this part of the residual liquid in the modified asphalt storage tank must be discharged through the filter valve at the bottom. Emulsion pump for modified asphalt storage tank There are basically two types of emulsion pumps for modified asphalt storage tank equipment on the market, gear pumps or centrifugal water pumps. Gear pumps can only discharge the liquid inside the pump through the connection flange of the pipeline. The centrifugal water pump for modified asphalt storage tanks uses its own sewage outlet for sewage treatment. The first four items of modified asphalt storage tanks with basic knowledge are basically discharged, and the modified asphalt storage tanks will focus on the latter types. Modified asphalt storage tank colloid mill There will also be residual emulsion or water inside the modified asphalt storage tank colloid mill. The gap between the stator and rotor of the colloid mill is within 1mm. If there is a little residual water in the modified asphalt storage tank, it will cause the accident of frozen modified asphalt storage tank. The residue in the colloid mill can be treated by loosening the connection bolts of the finished product pipeline.

Modified material bitumen stripper, if the definition is simple, is an bitumen stripper. If described in detail, modified materials such as rubber powder or other fillers are added to the bitumen stripper, or an bitumen stripper is used to Block chemical substances such as photooxygen catalysis. The first is to change the chemical composition of the bitumen stripper, and the second is to use modified materials to equip the stripper with a certain spatial network structure, thereby improving its performance. Modified bitumen strippers mainly include vulcanized rubber and thermoplastic polyurethane elastomer modified bitumen strippers, plastic and anti-corrosion coating modified bitumen strippers and polymer modified bitumen strippers.

Classification analysis of emulsion bitumen equipment is used to heat-melt bitumen. According to the actual cutting effect of mechanical equipment, it is loosened into a solution with demulsifier in the form of tiny droplets to form oil-in-water asphalt. Industrial equipment for lotions. Emulsion bitumen equipment can be divided into three types: portable, transportable and mobile according to the equipment, layout and maneuverability of the equipment.

With the continuous improvement of science and technology in my country, the application and popularization of bitumen emulsion equipment are also increasing. So how to check whether the configuration meets the standards? Only products that meet the standards can bring us benefits. We must pay attention to this issue. Next, please have a detailed understanding with our factory staff:
1. First of all, we need to check the modified emulsifier. If the gap between the bitumen emulsion colloid mill of the emulsifier will become larger during operation, we need to adjust it before continuous production;
2. Analyze the problem of the modifier. Under normal circumstances, we need to check whether the amount of modifier added is accurate. The time of addition should also adjust the pH value according to the difference in water quality used. This work needs to be operated by technical personnel;
3. Another major reason is caused by the problem of the bitumen emulsion configuration itself. When producing bitumen emulsion, it is necessary to check in advance whether the bitumen material used meets the quality standards.

Warm Mix Asphalt Basics: Warm mix asphalt additives are excellent modifiers for asphalt mixtures, available in two types: viscosity reducers and surfactants. Viscosity reducers are in powder or granular form with extremely low ash and moisture content and a low melting point. Surfactant-based additives come in both dry and wet forms, varying in color, but both are clear, sediment-free liquids with extremely stringent key parameters!
Comprehensive Performance Verification: From the basic properties of warm mix asphalt to temperature sensitivity and durability, every step is rigorously controlled! Mixture verification is also thorough, with volumetric parameters, mechanical properties, and road performance all meeting standards to ensure roads are both strong and durable!
Strict Quality Control: Factory inspection, type testing, and full-parameter testing ensure every batch of warm mix asphalt is of the highest quality! Sampling is also carefully managed; if a batch fails to meet standards, the sampling is doubled until the entire batch passes!
Remember the Storage and Transportation Standards: Moisture-proof, sealed, protected from light, and temperature-controlled; shelf life up to 24 months! In this way, warm mix admixtures can be readily available to support road construction!
This standard ensures that warm mix admixtures maintain excellent road performance while lowering the construction temperature, making them a true helper in road construction

Here is an introduction to the knowledge on construction quality control of modified rubber asphalt equipment. Let’s introduce this knowledge from three aspects. The details are as follows: The viscosity of the modified asphalt mixture of modified rubber asphalt equipment is relatively high, and the construction temperature of each process is The construction temperature requirements are higher than those of ordinary asphalt mixtures.

Energy conservation and environmental protection are also excellent ways for Chinese companies to break down foreign trade barriers. By the end of 2011, the annual fuel consumption of my country’s construction machinery products exceeded the total annual output value of construction machinery. Currently, market entry barriers in countries like the United States and Japan are rising, and emission standards are a primary concern among these trade barriers. Industry experts believe that energy conservation and emission reduction in the construction machinery industry are challenging, often hindered by technical bottlenecks. Therefore, increasing research and development efforts is an effective way to address this situation. Energy conservation and environmental protection are the inevitable trends in the development of China’s construction machinery industry.
Whether it is to reduce environmental burdens or break down foreign trade barriers, energy conservation and environmental protection will become the mainstream trend in the development of construction machinery. The future development of China’s construction machinery industry will place greater emphasis on transformation and upgrading, and energy conservation and environmental protection will be a key focus in its implementation strategies. Currently, construction machinery manufacturers are incorporating more energy-saving and environmental protection elements into their new products. At the just-concluded biennial Shanghai Bauma Show, renowned international construction machinery companies like Komatsu, Hyundai, and Volvo Construction Equipment, as well as Chinese construction machinery giants like Sany, XCMG, Zoomlion, and Liugong, showcased their latest equipment, all boasting enhanced energy-saving and environmental performance. This demonstrates that the future of construction machinery will inevitably be dominated by energy conservation and environmental protection. Construction machinery companies must prioritize their own efforts to achieve higher product efficiency and superior energy-saving and consumption-reduction performance.

1. Different production processes
Emulsified asphalt and asphalt are both extracted from petroleum, but their production processes are different. Asphalt is separated from crude oil by high-temperature treatment, and then processed through a series of complex processing processes such as distillation and fluidized hydrogenation. Emulsified asphalt, on the other hand, is made by adding an emulsifier, mechanical shearing or ultrasonic “emulsification” reaction, dispersing oil and water to form an emulsion, and then adding an appropriate amount of acid catalyst.
2. Different usage scenarios
Asphalt is suitable for paving in different places such as roads, bridges, airport runways, and parking lots. Emulsified asphalt is particularly suitable for use under more stringent conditions such as deep road repair and bridge deck waterproofing. Because emulsified asphalt produced by emulsification technology has better performance and can better adapt to complex usage environments.
3. Different characteristics
Asphalt is a black, viscous substance with fluffy fibers, a high melting point, high hardness, and easy aging. In comparison, emulsified asphalt is lighter in color, light gray or milky white, with moderate viscosity and uniformity, good adhesion, good water and weather resistance, and not easy to age.
4. Different use effects
Although asphalt works well on the road surface, it also has certain difficulties in construction and maintenance. Emulsified asphalt is more convenient to use and can be easily mixed with other materials during construction, so it is widely popular and has better use effects.
In summary, there are obvious differences between emulsified asphalt and asphalt in production process, usage scenarios, characteristics, and use effects, and appropriate materials need to be selected according to different needs.

Emulsified asphalt (ingredients: asphaltene and resin) heating tank is a new type of equipment for heating emulsified asphalt. Its appearance replaces the traditional thermal oil heating equipment, which brings great convenience to our users and improves work efficiency. Then let’s take a detailed look at how it is better than the traditional thermal oil heating equipment.
Emulsified asphalt (ingredients: asphaltene and resin) heating tank is another new type of emulsified asphalt heating storage equipment developed by technically separating the characteristics of traditional thermal oil heating emulsified asphalt tanks and internal heat part (part) rapid emulsified asphalt heating tanks. The automatic circulation program of the asphalt heating equipment enables the asphalt to automatically enter the heater, dust collector, induced draft fan, asphalt pump, asphalt temperature display, water level display, and steam generator as required.
It consists of pipeline and asphalt pump preheating system, pressure relief system steam combustion system, tank cleaning system, oil unloading tank installation, etc. All are installed on the tank body (inside) to form a compact integrated structure. It fully compensates for the shortcomings of traditional thermal oil heating equipment, such as long heating time and high energy consumption.

The engine is the source of power for the vehicle. If the synchronous sealing vehicle wants to perform normal construction operations, it must ensure that the engine is in good condition. Routine maintenance is an important means to effectively prevent engine failure. How to maintain it is determined by Xinxiang Junhua Special Vehicle Vehicles Co., Ltd. will take everyone to understand.

During the road construction process, asphalt spreaders also play an irreplaceable role. Let’s take a look at the main performance advantages of asphalt spreaders produced by Sinoroader and where their main contributions exist?
1. Manual/automatic control of spraying volume and working width. Each nozzle can be controlled individually, and the determinant nozzles can be freely combined to adjust the spraying width at will. Spreading control can be performed in the cab or the rear platform.
2. The automatic control system can measure the vehicle speed and automatically calculate the number of revolutions of the asphalt pump according to the input spreading volume, spraying width and asphalt type, and then automatically adjust the number of asphalt pumps through the system.
3. The vehicle-mounted rapid heating system (10-15℃/h) can improve the heating efficiency and reduce the construction auxiliary time and spreading temperature;
4. The flushing nozzle system can blow out the remaining asphalt in the nozzle through diesel and high-pressure air to prevent the asphalt from freezing in the nozzle and increase the service life of the nozzle.

The simple structure of rubber production equipment makes hot asphalt pavement recycling construction very easy to operate, especially for hot recycling. All construction equipment forms a complete construction line, so the construction process is relatively simple. So, what are the advantages of hot asphalt recycling technology?
1. The testing process is relatively complex during hot asphalt recycling construction. It requires testing the composition and content of concrete blocks of different sizes, which requires a significant amount of work and time. However, in general, most of the construction work in hot asphalt pavement recycling is done by large equipment, making the operation relatively simple.
2. Minimal impact on road transport. During hot asphalt recycling construction, only one road can be constructed at a time. It is not necessary to close the entire road; only the construction section needs to be closed, thus minimizing disruption to normal traffic. Furthermore, after the asphalt pavement is paved, traffic can be restored relatively quickly, repairing damaged surfaces without affecting normal traffic flow, effectively reducing losses.
3. The entire construction process of hot asphalt recycling is completed on-site, allowing for near-continuous use day and night after completion. This effectively saves time, enabling damaged road sections to be repaired and put back into operation quickly.
4. Cost-effectiveness: Hot asphalt recycling technology involves heating and melting damaged asphalt concrete, adding recycling agents day and night, and then applying the coating. This rationally utilizes resources, effectively reducing road maintenance costs and conserving resources.
5. Minimal environmental impact: Discarding asphalt into the natural environment causes significant pollution. In traditional asphalt pavement maintenance, asphalt concrete cannot be recycled and is simply discarded, resulting in a significant environmental impact. Hot asphalt recycling technology effectively avoids this problem.
The above summarizes the advantages of hot asphalt recycling technology. Asphalt is now a primary material in road construction, and we are all familiar with it and its use is widespread. We now have a considerable understanding of asphalt, and we hope this information is helpful!

Construction Condition Assessment
Base Layer Moisture Control
1. The base layer surface must be completely dry, without standing water or water accumulation.
After rain, the base layer must be drained to ensure no standing water.
The moisture content of the base layer must be controlled below 5%. Drying can be accelerated using a blower or natural air drying.
Low-lying areas with standing water must be filled to prevent the mixture from coming into contact with water and causing delamination.
Ambient Temperature Requirements
1. The ambient temperature for construction must meet the specifications.
The construction temperature for expressways and Class I highways must not be lower than 10℃.
The construction temperature for other highway grades must not be lower than 5℃. Paving should not be carried out during cold seasons or when rapid compaction cannot be guaranteed due to strong winds and temperature drops.
Weather Condition Assessment
1. Ensure there is no rainfall during construction.
Closely monitor the weather forecast before construction and schedule construction during periods without rain.
Construction should not be carried out within 24 hours after rain; wait until the base surface is completely dry.
Special measures must be taken when the relative humidity is higher than 80%.
Key Points for Construction Preparation
Material Selection and Treatment
1. Select water-resistant materials
Preferably use modified emulsified asphalt-based cold mix
Cement (1%–2%) can be added to improve water stability
Aggregates must be clean, dry, and have a moisture content ≤3%
2. Material Storage Requirements
Cold mixes should be stored in sealed containers to prevent moisture absorption and clumping. Emulsified asphalt in drums must be protected from rainwater infiltration. Sufficient rainproof materials such as plastic sheeting and rain shelters should be stocked. Equipment Commissioning and Preparation
