What are the main road uses of modified asphalt equipment?

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.

As a black road construction machinery, the synchronous chip sealer is the main equipment for highways, urban roads, airports, and port terminal facilities. Do you know what kind of synchronous chip sealer? What products do you have to choose from?
Asphalt dispensers are classified according to the purpose, operation mode, and drive mode of the asphalt pump. According to the purpose, asphalt dispensers can be divided into two types: road use and road construction use. The asphalt tank capacity of the asphalt dispenser used for road construction generally does not exceed 400L, while the asphalt tank capacity of the asphalt dispenser used for road construction is 3000-20000L.

There are many types of emulsified bitumen, and PC-2 is one of them, which is a spray-type emulsified bitumen. It is used for spraying oil through the base layer of granular materials and health care spraying on semi-rigid base layers. There is also the PA-2 type, which has the same purpose as the PC-2 type. The difference is that the PC-2 type is a cation, while the PA-2 type is an anion.

Bitumen decanter equipment can be placed in a complex system as an independent unit, replacing the existing heat source de-barreling method, or in parallel as a core component of a large set of equipment, or it can work independently to meet the requirements of small-scale construction operations.
The Sinoroader bitumen decanter device is mainly composed of a de-barreling box, a lifting mechanism, a hydraulic thruster and an electrical control system. The box is divided into two chambers, the upper chamber is a barreled bitumen melting chamber, and heating coils are evenly distributed around it. The heating pipe and the bitumen barrel mainly exchange heat in a radiation manner to achieve the purpose of bitumen de-barreling. Several guide rails are the tracks for the bitumen barrel to enter. The lower chamber is mainly to continue heating the bitumen removed from the barrel to make the temperature reach the suction pump temperature (100℃), and then the asphalt pump is pumped into the upper chamber. At the same time, an empty barrel is pushed out at the rear end outlet. There is also an oil tank on the platform at the entrance of the asphalt barrel to prevent the dripping bitumen from flowing out.
The inlet and outlet doors of the device adopt a spring automatic closing mechanism. The door can be automatically closed after the asphalt barrel is pushed in or out to reduce heat loss. A temperature gauge is installed at the asphalt outlet to observe the asphalt outlet temperature. The electrical control system can control the opening and closing of the hydraulic pump and the reversing of the electromagnetic reversing valve to realize the advance and retreat of the hydraulic cylinder. If the heating time is extended, a higher temperature can be obtained. The lifting mechanism adopts a cantilever structure. The bitumen barrel is lifted by an electric hoist, and then moved horizontally to place the bitumen barrel on the guide rail. A temperature gauge is installed at the outlet of the asphalt meltering equipment to observe its outlet temperature.

From three aspects, emulsion bitumen equipment has good economic performance:
First, energy saving. The kerosene or gasoline content in diluted asphalt can reach 50%, while the emulsion bitumen plant only contains 0-2%. This is a valuable saving behavior in the production and utilization of white fuel. By simply increasing the viscosity standard of asphalt by adding light oil solvent, asphalt can be poured and spread, and it is hoped that the light oil after use can evaporate into the atmosphere.
Second, versatility. There are many application methods for emulsion bitumen plants, and the appropriate method needs to be selected when applying it. The same emulsion can be used for large-scale sealing and can be used for small-scale pit repair work. Because they can be stored in tanks for a long time, they are very easy to use when applied in remote areas.
Third, it is easy to use. The professional spreading of emulsions requires professional equipment, such as spreaders. Small-area emulsion applications can be directly poured and spread by hand, such as small-area pit repair work, crack fillers, etc. Small quantities of cold mixes only require basic equipment.

In the field of road construction, the technical adaptability of emulsified asphalt production equipment directly affects the efficiency of the project. This article analyzes the technical path for efficient production from three dimensions: equipment selection, core components, and cross-industry technology migration.
I. Equipment type and technical adaptability
Mainstream equipment is divided into mobile and fixed types. The ZMLR6000 equipment adopts a 304 stainless steel tank and a thermal oil heating system. The ±0.5% ratio accuracy meets the fineness requirements of high-grade roads ≤5μm, which is suitable for field operations. The YK6 unit realizes dual-mode heating through the RH6 colloid mill, heats to 100℃ within 45 minutes, supports continuous production of 20%-70% solid content, and has a daily production capacity of 120 tons, which is more suitable for small and medium-sized projects.
II. Core component technology breakthroughs
1. High-speed shear system: The German imported colloid mill adopts a stepped internal tooth structure with a rotation speed of 10,000rpm. The 0.05mm shear gap ensures that the asphalt particles are refined to 1-5μm, and the emulsion stability is improved by 30%.
2. Temperature control and energy-saving design: The waste heat recovery system reduces energy consumption by 30%, the 10㎡ heat exchanger achieves closed-loop energy conservation, and the ±0.5℃ temperature control accuracy can simulate the long-term aging process of asphalt.
3. Intelligent control system: The Internet of Things module supports remote early warning, and the SCADA system integrates 32 temperature sensors. The temperature difference is monitored in real time through dynamic thermal imaging, and the solid content deviation is controlled within ±1%.

According to statistics, among the high-grade highways that have been built and opened to traffic in my country, about 80% are asphalt pavements. However, with the development of time, the influence of various climatic and environmental factors, and the high-intensity driving load, the asphalt pavement will have different degrees of degradation or damage. Pavement maintenance is to take effective technical means to slow down this degradation, so that the pavement can provide good service quality during its service life.

In the application, the asphalt spreader has intelligent asphalt spreading rate and low investment, low power consumption, low cost, high thermal efficiency. The asphalt spreader can reach the temperature required for construction in a short time. It is easy to use and move. It can be operated by one person. A set of electric heaters is a bit expensive. In the production process of the asphalt spreader, water, as a production material, needs to be heated from room temperature to about 55°C. The evaporation heat of the asphalt spreader is transferred to the drainage. It is found that after the emulsified asphalt is produced for 5 tons, the asphalt spreader is accompanied by a significant increase in the temperature of the cooling circulating water. The production water uses cooling circulating water, and the water basically does not need to be heated. It can save 1/2 of the fuel simply from the energy.

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.

2. Slurry Material Laying: The slurry material is laid on the road surface, ensuring it is evenly applied and without any gaps.
3. Compaction: After the slurry material is laid, it is compacted using a roller to ensure it is firmly bonded to the road surface.
IV. Application and Benefits of Slurry Seal Treatment
Slurry seal treatment is widely used in practical projects, and its benefits are primarily reflected in the following aspects:
1. Improving Pavement Performance: Slurry seal treatment can effectively enhance pavement performance, such as skid resistance, wear resistance, and water resistance, improving pavement performance.
2. Extending Pavement Life: Slurry seal treatment effectively protects the pavement, delaying aging and damage, and extending its service life.
3. Improving Pavement Aesthetics: Slurry seal treatment creates a smooth and aesthetically pleasing surface, enhancing the overall appearance of the pavement.
In summary, slurry seal, as an economical and environmentally friendly pavement surface treatment method, has broad application prospects in pavement engineering. With the continuous advancement of technology and the continuous upgrading of materials, slurry seal will play an even greater role in the field of pavement maintenance.

What are the methods for repairing cracks in asphalt pavement? Asphalt pavement is a widely used pavement material in modern road construction, with high strength and durability. However, as time goes by and the frequency of use increases, cracks will inevitably appear in asphalt pavement. So, what are the methods for repairing cracks in asphalt pavement?
What are the methods for repairing cracks in asphalt pavement?
1. Oil filling repair method
This repair method is mainly for smaller cracks or cracks. First, clean the damaged part, then soften the asphalt pavement with a liquefied gas tank, and then pour the thick asphalt into the cracks, and flatten it with a soldering iron, and then carry out normal pavement maintenance. The oil filling repair method is one of the methods for repairing cracks in asphalt pavement, and it is also one of the most commonly used repair methods.
2. Emulsified asphalt seal repair method
This method is mainly for minor cracks or loose cracks. Use a machine to apply a layer of emulsified asphalt on the ground, then sprinkle some stone chips, and finally roll it. This repair method can be constructed on rainy days, with a fast construction speed, and can handle minor crack problems.
3. Cold-patch asphalt mixture repair method
Cold-patch asphalt mixture is one of the asphalt pavement repair materials with good adhesion, wear resistance, and skid resistance. This material is suitable for the repair of various asphalt pavements. It is easy to use and can be quickly opened to traffic after repair, reducing construction time. The color of the cold-patch asphalt mixture is also very different from the original pavement, which can be clearly distinguished and convenient for construction operations.

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 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.

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 heat transfer 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.

Asphalt spreading truck is a kind of black ground construction machinery. It is an important equipment in the logistics construction of roads, municipal roads, airports and ports. This equipment is mainly used to spray different types of asphalt on the ground to meet the construction requirements of different levels of ground oil permeable layer, sticky layer, left and right permeable layer, fog permeable layer, etc.

The advantages of Sinoroader bitumen decanter equipment over similar domestic equipment are reflected in the following points:
1. The equipment produces 8-10t/hour, with an automatic telescopic sealed container structure. It uses an electric hoist to lift the asphalt barrel at the inlet guide tube. Start to control the hydraulic cart forward button, which will promote the barrel push (push and slide into the barrel). It is a 1300mm hydraulic cylinder with a 7.5-ton top thrust. The device has a beautiful appearance, reasonable layout, compactness, stable performance, and is suitable for production under various industrial and mining conditions.
2. Fast barrel removal: According to the principle of layered heating, it adopts four-layer thermal oil heating technology, a single inlet and outlet, and high thermal efficiency of heating; at the same time, it uses the waste heat of combustion gas for two heatings and efficient use of energy; the barrel body uses high-quality rock wool insulation material.
3. Good environmental protection: closed structure, no pollution.
4. No barrel hanging: The upper part of the asphalt barrel is hot, and each is directly affected by the thermal oil heating pipe. The barrel wall directly receives the heat dissipation of the heating coil, and the barrel is clean and fast, which will not cause waste of asphalt barrel hanging.
5. Strong adaptability: Suitable for imported and domestic barrels, and the deformation of asphalt barrels will not affect production.
6. Good dehydration: Use a large-displacement asphalt pump for internal circulation, stirring, water vapor overflows, and is naturally discharged from the exhaust port. After dehydration, asphalt can be directly used to produce asphalt mixture or used as matrix asphalt.
7. Automatic slag removal: This set of equipment has an automatic slag removal function. The filter device sets the asphalt circulation pipeline through the filter, which can automatically remove the barreled asphalt slag.
8. Safe and reliable: The equipment adopts an automatic control system, an automatic ignition burner import, can automatically control the temperature according to the temperature, and is equipped with corresponding monitoring instruments.
9. Convenient relocation: The whole machine is assembled with large components, which is easy to move and quick to assemble.

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

I believe that many people already know about synchronous gravel sealing. But when asked under what circumstances synchronous gravel sealing is suitable, many people cannot tell.
Under what circumstances is synchronous gravel sealing more suitable? According to the technical specifications for the construction of simultaneous gravel sealing, simultaneous gravel sealing can be used for the following disease types:

Emulsified asphalt equipment is an indispensable equipment in road construction and one of the basic equipment for waterproof coatings. What are the components of emulsified asphalt equipment? Today, we will explain the various parts of emulsified asphalt equipment in detail.

In modern highway maintenance work, how to repair asphalt pavement quickly and effectively has become one of the key issues. As an advanced repair technology, cold patching technology is very popular because of its convenient construction and remarkable effects.
What is the cold patching process?
Cold patching process, as the name suggests, refers to a technical method for repairing asphalt pavement without heating. This process uses a specially proportioned cold-patch asphalt mixture. This material can maintain good fluidity and adhesion even at lower temperatures, thus ensuring the quality of the repair.
Advantages of cold patching process
Fast construction: Cold patching materials can be directly applied to damaged areas without preheating, and are immediately open to traffic, greatly shortening repair time.
All-weather construction: Whether in hot summer or cold winter, cold patching materials can be effectively constructed and are not affected by the weather.
Easy to operate: Thanks to its good working properties, even small damaged areas can be repaired easily.
Environmentally friendly: The construction process reduces environmental pollution and is in line with the concept of green construction.
Application scenarios
The cold patching process is suitable for various types of pavement repair work, especially those places where traffic needs to be restored quickly, such as urban main roads, highway ramps, etc. In addition, the cold patching process is also an ideal choice for remote areas or situations where professional heating equipment is lacking.
In short, the cold patching process has occupied a place in the field of rapid repair of asphalt pavement with its unique advantages and has become an indispensable part of modern highway maintenance.

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.

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.

Asphalt spreader is an irreplaceable tool for highway maintenance. Asphalt spreader is an irreplaceable tool for highway maintenance. Highway maintenance is divided into four categories according to the nature of the project, scale, and technical complexity: minor repair, medium repair, major repair, and improvement. Specific classification:
(1) Minor repair and maintenance project: preventive maintenance and repair of slightly damaged parts of the highway and all its engineering facilities to keep them in good condition. It is usually planned and carried out daily by the maintenance team within the annual minor repair and maintenance quota funds on a monthly (ten-day) basis.
(2) Medium repair project: regular repair and reinforcement of general wear and tear and local damage of highway engineering facilities to restore them to their original state. It is usually planned and implemented by grassroots road maintenance agencies on an annual (seasonal) basis.
(3) Major repair project: periodic comprehensive repair of major damage to highway facilities to fully restore them to the original design standards, or local improvements and individual additions within the original technical level to gradually improve the highway’s traffic capacity. It is usually organized and implemented by grassroots road maintenance agencies or with the help of their superior agencies according to the approved annual project budget.
(4) Improvement projects are large projects that improve the technical level of roads and their engineering facilities in stages and sections due to their inability to meet traffic volume and load requirements, or significantly improve traffic capacity through improvements. It is usually organized and implemented or completed through bidding by regional road maintenance agencies or provincial road maintenance agencies according to the approved plan and design budget. As a manufacturer of asphalt spreaders, we welcome you to visit us.

With the rapid development of our country’s social development and the continuous development of economic and information technology, modern highway construction is also developing rapidly, and the requirements for ground structural materials are becoming higher and higher, and Asphalt concrete bonding raw materials are inseparable from modified asphalt equipment. So besides these influencing factors, what other reasons does the company have that people don’t understand? Let’s analyze it together.
There are some asphalt concrete equipment on the market, because they have not solved the problem of asphalt clogging before grinding, there are not enough preparation equipment and grinding equipment, the structure is unscientific, and the entire grinding process cannot achieve a certain particle size, resulting in modification. The product productivity of asphalt equipment is low and the product quality is unstable. It requires continuous grinding for a long time, creating problems. This will not only greatly increase energy consumption, increase costs, make product quality unstable, and affect the speed of highway construction.

There are many types of bitumen emulsifiers, and there are many classification methods. For specific classifications, please refer to previous articles. The raw materials required for the production of emulsion bitumen are: bitumen, water and bitumen emulsifier. High-standard emulsion bitumen requires adding additives and adjusting acid. According to whether acid adjustment is needed in the emulsion bitumen production process, it can be divided into two categories: emulsion bitumen that requires acid adjustment and emulsion bitumen that does not require acid adjustment.

The slurry seal truck is mainly used for preventive maintenance of municipal pavement. It can improve the quality of the seal, effectively improve the integrity and crack resistance of the seal, extend the service life, and the construction process is simple without adding too many construction links. It is a kind of road maintenance equipment that has become quite popular in recent years.

Emulsified asphalt is to melt the asphalt and disperse it in a water solution containing a certain amount of emulsifier in the form of tiny droplets through the action of emulsifier and machinery to form an oil-in-water asphalt emulsion. This emulsion is in the form of dry liquid at room temperature. Modified emulsified asphalt refers to a modified asphalt mixed emulsion with certain characteristics prepared by blending, mixing and preparing it with emulsified asphalt as the base material and asphalt modification material as the external modification material under a certain process flow. This mixed emulsion is called modified emulsified asphalt.
The modified production process of emulsified asphalt can be divided into four categories:
1. Adding latex modifier after making emulsified asphalt, that is, emulsification first and then modification;
The production process is to grind the hot asphalt and emulsifier soap solution together through colloid mill to make ordinary emulsified asphalt, and then add the latex modifier to the emulsified asphalt through mechanical stirring to make modified emulsified asphalt. The advantage of this method is that it does not require high equipment, and the disadvantage is that it is suitable for latex modifiers.
2. The latex modifier is mixed into the emulsifier aqueous solution, and then it enters the colloid mill together with the asphalt to produce modified emulsified asphalt;
3. The latex modifier, emulsifier aqueous solution, and asphalt are put into the colloid mill at the same time to produce modified emulsified asphalt (the two methods 2 and 3 can be collectively referred to as emulsification and modification);
The modifier is mixed into the emulsifier soap solution, and then the “modified” soap solution and asphalt are put into the colloid mill together to make modified emulsified asphalt; or the modifier is not pre-added to the emulsifier soap solution, but is placed in a tank separately, and finally mixed with the emulsifier, acid, water, etc. in the pumping pipeline and then enters the colloid mill together with the hot asphalt.
The method of adding latex modifier to the soap tank has the advantage that it is exactly the same as the process of producing ordinary emulsified asphalt, and no changes are required to the production equipment; the disadvantage is that when using this method to produce modified emulsified asphalt, the metering of the modifier is subject to certain restrictions, and the modifier latex is required to be able to withstand the pH value of the soap solution. The method of directly connecting the latex modifier to the colloid mill through a pipeline can overcome the above disadvantages, but it requires necessary improvements to the ordinary emulsified asphalt equipment before it can be used for the production of modified emulsified asphalt.
4. Emulsify the modified asphalt to produce emulsified modified asphalt.
The ready-made modified asphalt is heated to a certain temperature, becomes a flowing state, and then enters the colloid mill together with the soap solution to make emulsified modified asphalt. In the entire asphalt production process, due to the high viscosity characteristics of the asphalt itself and the high temperature environment required for production, various high-performance pumps and valves play a vital role in the asphalt transportation process.

The container-type emulsified bitumen equipment hot-melts the base cold-mix colored bitumen and disperses it through the equipment into small cold-mix colored bitumen particles in an aqueous solution containing emulsifier to form a liquid cold-mix colored bitumen material.

Preparation items for micro-surfacing slurry sealing: materials, construction machinery (micro-surfacing paver) and other auxiliary equipment.
The micro-surface slurry seal requires emulsified asphalt and stone that meet the standards. The metering system of the micro-surfacing paver needs to be calibrated before construction. The production of emulsified asphalt requires asphalt heating tanks, emulsified asphalt production equipment (capable of producing asphalt content greater than or equal to 60%), and emulsified asphalt finished product tanks. In terms of stone, mineral screening machines, loaders, forklifts, etc. are needed to screen out oversized stones.
The tests required include emulsification test, screening test, mixing test and the equipment and technical personnel required to do these tests.
