The combination of time-reliable hydraulic transmission components and Meitong’s control system can make the equipment instantly start from zero. Spraying starts in line, stable and reliable.
2. Duplex sealing structure
The sealing process of this equipment is a three-layer simultaneous and continuous construction process of one layer of asphalt + one layer of fiber + one layer of asphalt, forming a layer of interactive dense network winding structure, which fully meets the user’s construction requirements.

What key points should be paid attention to when feeding emulsified asphalt equipment? When it comes to emulsified asphalt equipment, I don’t know how much you know about it? What should you pay attention to when adding materials?
The black anti-static tweezers grinding wheel of the emulsified asphalt equipment does not have a heated collet. Before use, you must add the appropriate amount of diesel and let the black anti-static tweezers circulate for 3 to 5 minutes to generate heat (the temperature after operation is 80 ~100 degrees) open the stop valve on the oil delivery pipe to drain the diesel engine in the engine. The temperature of the black anti-static tweezers grinding wheel must be around 80 to 100 degrees before the material can be loaded and put into production. If there is a heated collet, the grinding wheel must be heated before starting, and then the material is loaded and put into production.

The fine surface is made of stone with a single particle size, which has high wear resistance and anti-slip properties. The construction of the fine surface adopts mechanized construction, which requires less manual labor and has the characteristics of fast construction speed, anti-skid and noise reduction.
The special bonding material for fine surfaces produced by Sinoroader Group has the characteristics of good bonding performance and good durability. The specific construction process is roughly as follows:

Asphalt spreader vehicle is an intelligent and automated high-tech product that specializes in spreading emulsified asphalt, diluted asphalt, hot asphalt, high-viscosity modified asphalt, etc.
Asphalt spreader is used for spreading the penetration oil, waterproof layer, and bonding layer of the bottom layer of the asphalt pavement of high-grade highways. The spreader consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, an ignition system, a control system, a pneumatic system, and an operating platform.
Asphalt spreader is cumbersome to operate. On the basis of absorbing various technologies of similar products at home and abroad, it increases the quality technology content of construction and the humanized design of outstanding improvement of construction conditions and construction environment. Its reasonable and reliable design ensures the uniformity of asphalt spreading, the computer control is stable and reliable, and the technical performance of the whole vehicle has reached an advanced level.

Asphalt mixing plant is one of the main equipment for producing asphalt concrete. It can mix asphalt, gravel, cement and other materials together in a certain proportion to obtain the products required for highway construction. In order to ensure its operating effect, the asphalt mixing station also needs to be powered on for trial operation before it is officially put into work.

Emulsified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first ensure the safe use of emulsified asphalt equipment to fully demonstrate its performance; modified asphalt equipment is an asphalt binder made by adding rubber, resin, high molecular polymer, ground rubber powder or other fillers and other admixtures (modifiers), or taking measures such as mild oxidation of asphalt to improve the performance of asphalt or asphalt mixture; So how much do you know about the safe use and operation of modified asphalt equipment? Today, the editor will tell you;
Placement: The modified asphalt equipment should be placed on a flat place, and the front axle wheel should be fixed with sleepers and the tires should be dangling to ensure the stability of the machine during work.
Regularly inspect whether the mixer blades are deformed and whether the screws are loose.
Inspect whether the running direction of the mixing barrel is consistent with the arrow; if not, please replace the positive and negative poles of the wiring.
Before powering on, you should inspect and test run the empty vehicle, check for leakage, and check the idling of the mixing barrel. The normal speed is about 3 times faster when the empty vehicle is full. If the speed is wrong, you should stop the machine and check the asphalt tank.
Note: After the asphalt material is mixed, it is best to stop the machine for one hour, clean the drain material in the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water accumulation in the barrel to prevent the formula from changing, and the blades are prone to rust. During use, everyone should pay attention to these small links to avoid unnecessary losses to their work.

Asphalt used to pave roads. It can be obtained by regular vacuum distillation of crude oil with appropriate properties, and can also be obtained by shallow oxidation of vacuum residue or propane deasphalting process. It can also be prepared by mixing asphalt of different duction and injection degree

The modified asphalt equipment produced by Sinoroader can produce SBS, rubber powder, SBR, and PE modified asphalt manually and automatically. Some of its configurations and uses are as follows:
1. Filter: The specially made asphalt filter can effectively filter impurities and foreign matter in the high-temperature matrix asphalt to prevent damage to subsequent equipment.
2. Matrix asphalt heater: The spiral plate or shell and tube heat exchanger is used to quickly heat the matrix asphalt through heat transfer oil to meet the needs of the production process. Heating in a sealed tank avoids the aging of asphalt due to long-term high-temperature heating and exposure to the air. The sulfide produced during the production process is quite limited, reducing environmental pollution.
3. Modifier air delivery or spiral addition system: The modifier manually poured into the pouring hopper is delivered to the asphalt batching tank by wind or spiral. It can be equipped with a metering system.
4. Stabilizer automatic or manual addition system: It can be equipped with a metering system.

Emulsified asphalt is an aqueous suspension of asphalt particles with high interfacial energy. This suspension state is thermodynamically unstable and has the potential to reduce its interfacial area (i.e., through the coagulation process) to a stable state. Preventing this coagulation state (dispersion destruction) is the stabilization effect of the emulsifier protective layer. The stability of emulsified asphalt refers to the ability of asphalt particles to aggregate and cause phase separation, and also refers to the time required for emulsified asphalt to reach equilibrium. That is, the time for asphalt particles to aggregate and separate from water. How can we increase this time? How to prevent emulsified asphalt from demulsifying?

Precautions during the production of emulsified bitumen equipment. How much do you know about this information? Let’s learn more about it:
When the emulsified bitumen equipment is in production, the viscosity of the bitumen decreases with the increase of temperature. For every 12℃ increase, its dynamic viscosity decreases by about one time. During production, the base bitumen should be heated to liquid state before emulsification. In addition, in order to adapt to the emulsification capacity of the colloid mill, the base bitumen dynamic viscosity is generally controlled to be about 200cst. The lower the temperature, the higher the viscosity, which increases the burden on the bitumen pump and the colloid mill, making it difficult to emulsify; but on the other hand, in order to prevent the demulsification caused by excessive vaporization and evaporation of water in the finished product during the production of emulsified bitumen, it is impossible to heat the base bitumen temperature too high. Generally, the finished product temperature at the outlet of the colloid mill should be controlled to be less than 85℃.

We need to prepare a lot of work when using modified asphalt equipment. What kind of work do we need to prepare? Next, let me briefly introduce the relevant knowledge points.
1. Heat transfer oil heats and insulates the modified asphalt equipment and nozzle. After spraying, the asphalt pump and nozzle do not need to be cleaned with diesel. Use high-pressure air to press the asphalt in the pipeline and spray pipe back to the tank, and then blow the nozzle; use heat transfer oil to keep warm, so that the pipeline and nozzle are smooth and unobstructed. 2. Various asphalts can be spread: high-viscosity asphalt, hot asphalt, emulsified asphalt, etc.; the spreading width can be freely adjusted, each nozzle can be controlled separately, and the maximum spraying width is up to 6m. Flexible handheld spray guns can be used to spray asphalt on corners. 3. Excellent thermal insulation performance, average cooling ≤1-2℃/h. 4. Convenient loading and unloading function. In addition to filling asphalt from the asphalt tank port, hot asphalt can be sucked out by itself, and external asphalt can also be pumped and transferred. 5. The modified asphalt equipment is evenly spread, and the nozzle design can be used for triple overlapping spraying.
The above are the relevant knowledge points of modified asphalt equipment. I hope the above content can be helpful to everyone. Thank you for your viewing and support. More information will be sorted out for you later. Please pay attention to our website updates.

Precautions for checking emulsified asphalt equipment
Sinoroader emulsified asphalt pavement engineering common equipment, now has gradually been widely used.
We all know that before any equipment is used, the equipment should be preliminarily inspected to check whether the installation is normal, and then put into use. The use of modified asphalt modified asphalt production equipment can also extend the peak season. The modified asphalt and stone water machine can be mixed with wet stone to form a continuous film under the surface conditions of low-temperature asphalt and stone. The viscosity of the asphalt is low and the viscosity of the emulsified asphalt is low. Wet film below 10 degrees.

To ensure good operation of asphalt melting equipment and extend its service life, regular maintenance and repairs are required. The following are specific maintenance and repair steps:
First, various parts of the equipment, including heating elements, pipes, valves, etc., need to be inspected regularly to make sure they are not worn or damaged. If any problems are found, they should be repaired or replaced immediately.

Asphalt mixture mixing equipment is a factory-style complete set of equipment that mixes dry and heated aggregates of different particle sizes, fillers and asphalt according to the designed mix ratio at a specified temperature into a uniform mixture. It is widely used in high-grade highways and urban roads. , airports, docks, parking lots and other engineering construction. It is a key equipment for asphalt pavement construction, and its performance directly affects the quality of asphalt pavement.
Generally, there are two types of asphalt concrete mixing equipment: intermittent type and continuous type. The continuous process flow is simple and the equipment is simplified. As for the intermittent forced mixing equipment, due to the secondary screening of aggregates, various components are measured in batches, and forced stirring and mixing can reliably ensure gradation, and the measurement of powder and asphalt can also achieve very high accuracy; so the mixing equipment The asphalt mixture produced is of high quality and can meet various construction requirements.

The heating principle of asphalt decanter equipment is to heat, melt and decanter the asphalt through the heating plate. It is mainly composed of de-barreling box, lifting system, propeller and electrical control system.
The box of asphalt decanter plant is divided into upper and lower chambers. The upper chamber is the asphalt melting chamber, which is densely covered with heat transfer oil heating coils or hot air heating pipes. The asphalt is melted and removed from the barrel by heat. The hoisting hook is installed on the gantry, and a barrel grabber is hung. The asphalt barrel is lifted by the electric winch, and then the asphalt barrel is placed on the guide rail by horizontal movement. Then the propeller pushes the barrel into the upper chamber through two guide rails, and an empty barrel is pushed out at the rear end outlet.
An anti-drip oil tank is provided at the entrance of the asphalt barrel. The asphalt enters the lower chamber of the box and is continuously heated to a temperature of about 100 to be transported, and then pumped into the asphalt tank by the asphalt pump. The lower chamber can also be used as an asphalt heating tank.
The asphalt decanter plant has the characteristics of not being restricted by the construction environment, strong adaptability and extremely low failure rate. If large production is required, multiple units can be assembled.

Asphalt anti-sticking release agent is a product used in the construction of hot asphalt mixture to solve the asphalt anti-sticking problem. It is used to replace diesel and vegetable oil! There are all kinds of things about the effect of asphalt anti-sticking release agent. How to use asphalt anti-sticking release agent?
Before use, stir the release agent evenly, spray or apply the original liquid evenly on the surface of construction equipment such as rubber-wheeled rollers, transport carriages, paver hoppers, ironing plates, etc.; or add water to the roller water tank after dilution, stir evenly and spray automatically for use.
When preparing to start construction, when the roller tires are cool or the temperature is low, you should first apply the roller tires with the release agent original liquid, and then start rolling. At the beginning, you need to apply more release agent. After the temperature of the tires rises, you can apply it normally or less. If you use intermittent spraying of release agent, you should spray more frequently at the beginning of construction.
When adding water, we recommend a ratio of 10-15 times. It will be better to use 10 times the water ratio. If you think the cost is high and want to add more water, it is also possible, but try to use less than 15 times the water ratio. If it is modified asphalt, it is recommended to use less than 8 times, and 7 times the water ratio is recommended.

Microsurfacing is a thin layer of overlay placed on old asphalt pavement and is a type of preventive maintenance process. The purpose of microsurfacing is road maintenance. After micro-surface paving, it can repair cracks in the original road surface, waterproof and beautify the road surface.
The construction method of micro surfacing is: using a micro surfacing paver to evenly spread modified emulsified asphalt, a certain grade of mineral materials, water and other additives on the road surface in a certain proportion.

Gravel Synchronized seal Trucks are essential road construction equipment. Regular maintenance and care are essential to ensure proper operation and extend their service life. This article provides a maintenance and care guide for Gravel Synchronized seal Trucks to help users manage their equipment correctly on a daily basis.
Cleaning and Lubrication:
Gravel Synchronized seal Trucks accumulate dust, sand, and other impurities during use, so regular cleaning is crucial. Use a high-pressure water jet or detergent to thoroughly clean the vehicle, especially the hydraulic system and feed mechanism.
Regularly check the hydraulic system fluid to ensure cleanliness and proper fill level. Replace the hydraulic fluid according to the manufacturer’s recommendations and regularly check the fluid viscosity and pressure.
Inspection and Repair:
Regularly inspect key components of the gravel truck, such as the hydraulic cylinder, conveyor belt, and vibrator. Ensure they are in good working condition and free of leaks, looseness, or wear.
Inspect the feed port and distribution mechanism to ensure even discharge and distribution of gravel. Repair or replace any damaged, clogged, or loose components. Check the vehicle’s tires and brake system to ensure they are in good condition. Replace tires as needed and adjust and maintain the brake system.
Regular Maintenance:
Develop a regular maintenance schedule based on the equipment manufacturer’s maintenance manual. This includes replacing filters, cleaning or replacing the air filter, and inspecting and adjusting the drive chain.
Regularly check the electrical system and instrument panel to ensure the accuracy and display of the instruments.
Cooperate with professionals for regular comprehensive inspections and maintenance, including pressure testing the hydraulic system and inspecting and adjusting the drive system.
Proper maintenance and care can keep your gravel truck in good working condition, improving construction efficiency and extending its lifespan. Users should follow the manufacturer’s requirements and instructions to develop a reasonable maintenance schedule. During use, be aware of any abnormalities and promptly address and repair them.

We should select products that meet the specifications, and we should not select raw materials that do not meet the specifications. The other thing is the operation technology of asphalt heating equipment. Skilled operation technology is the most important, and training is required before taking up the post.
In recent years, with the continuous development of various industries, the production of various equipment including modified asphalt equipment has been further developed and applied. Professionals introduced that in the process of using modified asphalt equipment for production, the terminal control system implements full automatic control of medium weight, working temperature, working flow, valve opening and closing, etc., thereby ensuring the quality of modified asphalt and greatly improving production efficiency. Now Shandong Duxiu Factory will explain the operating advantages of modified asphalt equipment to customers:
The base asphalt is heated to 150-170℃ in the rapid heating tank and then enters the blending tank to mix with the modifier fed in through the feeding device. The asphalt pump at the bottom of the blending tank then sends it to the colloid mill for high-speed grinding and shearing, so that the modifier and base asphalt are fully dissolved in extremely small particles, thereby improving the various properties of the asphalt. The finished modified asphalt after high-speed shearing and grinding enters the finished product development tank at the rear for direct use.

Emulsified asphalt can be spread by mechanical spreading and manual spreading. Different spreading methods will have different effects on pavement performance, so it is very important to choose the right spreading method. At the same time, maintenance and management after spreading are equally important to ensure the safety and durability of the pavement.
Emulsified asphalt is a common pavement material that is widely used in road construction and maintenance. There are two main ways to spread emulsified asphalt: mechanical spreading and manual spreading. Mechanical spreading generally uses a special spreading vehicle that can quickly and evenly spread emulsified asphalt. Manual spreading is carried out by workers using tools such as brushes or rollers, which is suitable for pavement treatment in small areas or special areas.
Different spreading methods also have different effects on pavement performance. Mechanical spreading can quickly complete large-area treatment and spread evenly, which is conducive to ensuring the flatness and anti-skid properties of the pavement. Manual spreading can more finely treat special areas such as shoulders and intersections to improve the overall performance of the pavement.

For the relevant knowledge of modified asphalt equipment, we have more or less introduced it in the above articles. I believe that most users also have some simple understanding of it. Today we also mastered:
In order to meet the different requirements of customers, the configuration and process of the equipment produced by the manufacturers of modified asphalt equipment are diversified. There are fixed production types, mobile types, and imported main machines, but the imported main machines are expensive, so most customers configure domestic pipeline emulsifiers or colloid mills. In terms of the degree of automation, there are fully automatic production and semi-automatic production. Regardless of the form of production, each has its own advantages and disadvantages. What kind of process and configuration is used depends on the annual production volume and the customer’s requirements for equipment, product performance requirements and other factors. I hope that these introductions can help users choose to a certain extent.

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.

From the current point of view, road construction machinery has bottomed out and asphalt meltering equipment has risen rapidly. In recent years, highway construction and maintenance departments have a strong awareness of using asphalt mixing equipment, especially in developed coastal areas such as Beijing, Shanghai, Jiangsu, Zhejiang, etc. In addition, these regions have a fast economic growth rate, relatively developed industry, and strong comprehensive economic strength. Therefore, the consumption of asphalt mixing equipments in these regions has always been at the forefront of the country. With the rapid development of highway construction and the increase in demand for asphalt, barreled asphalt has been widely used for its convenient transportation and easy storage. In particular, most of the high-performance imported asphalt used in high-grade highways is in barrel form, which requires an asphalt meltering equipment with fast melting speed, clean de-barreling, and can prevent asphalt aging. my country’s highway construction has achieved remarkable results, among which mechanized production has contributed greatly. Different types of asphalt mixers and bitumen meltering equipment are selected for the characteristics of large highway pavement construction and tight construction period. With the rapid development of my country’s economy, the further extension of expressways, and the large-scale development of western construction, the central and western regions have become new investment hotspots. While paying attention to the market in the developed eastern regions, domestic road construction machinery manufacturers have also increased their efforts to develop the central and western markets, creating new highlights for the domestic asphalt mixing plants consumer market. In summary, my country’s asphalt mixing plant sales market has begun to move westward with the westward movement of investment hotspots. As the market center of gravity gradually shifts westward, the market in the western region is gradually heating up. The self-heating integrated structure, hot air barrel melting and bitumen barrel flipping technology in the asphalt barrel removal equipment are our company’s self-heating integrated structure. The thermal oil furnace used in the old equipment is perfectly integrated with the asphalt barrel removal equipment body, which reduces the volume of the entire set of equipment, greatly reduces equipment investment, saves equipment space and transfer transportation costs.

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.

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.

Modified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first use the modified asphalt equipment safely to fully demonstrate its performance. So how much do you know about the safe use and operation of modified asphalt equipment? Today, Sinoroader will explain it in detail:
1. Placement: The modified asphalt equipment should be placed on a flat place, and the front axle wheel should be fixed with sleepers and the tires should be dangling to ensure that the machine does not move around during operation.
2. Check regularly whether the mixer blades are deformed and whether the screws are loose.
3. Check whether the running direction of the mixing barrel is consistent with the arrow. If not, please replace the positive and negative poles of the wiring.
4. Before powering on, check for empty vehicle trial operation, check for leakage, and check the idling of the mixing barrel. The normal speed is about 3 times faster when the empty vehicle is full. If the speed is wrong, stop the car for verification.
5. If the asphalt material is stopped for one hour after mixing, clean the mixing barrel, pour in clean water, and clean the mortar. Then drain the water, remember that there must be no water in the bucket to prevent the formula from changing, and even rust on the pages and other links. During use, everyone should pay attention to some small links to avoid unnecessary losses in their work.

With the development of science and technology, the emergence of emulsified asphalt tanks has brought great convenience to our work, and is widely used in every site. So what issues need to be paid attention to when filling emulsified asphalt tanks? Below, the editor will introduce to you the relevant knowledge structure diagram, hoping to be of some help to you.
