Never stop, escorting the quality of road construction
Inheriting decades of technical accumulation, asphalt mixing station has become an indispensable part of building and maintaining high-level roads. This seemingly ordinary device carries the important mission of ensuring road safety and improving driving experience. As the core technology of modern road engineering construction, asphalt mixing station goes all out to continuously strive for a better, safer and more efficient travel environment.
Fast drive, tenacious progress
Asphalt mixing station plays a role in road engineering. It uses mature technology and processes to ensure the smooth progress of road construction with efficient mixing capacity and stable production quality. From conveying raw materials to the precise proportion of oil and aggregates, to the uniform mixing of the final product, the asphalt mixing station, with its professional working attitude, ensures the quality and stability of road materials, and provides a solid foundation for the construction of high-standard road projects.
Innovation leads, environmental protection takes the lead
Asphalt mixing station plays an important role in promoting sustainable development. Faced with increasingly urgent environmental protection requirements, mixing stations continue to innovate technology, improve production efficiency, and also pay attention to environmental protection responsibilities. By introducing advanced dust removal and purification devices, intelligent equipment control systems and combustion equipment, the asphalt mixing station effectively reduces environmental pollution and makes positive contributions to protecting the surrounding ecological environment.

We have conducted in-depth research on asphalt distributors and have accumulated a lot of production technology experience. We have conducted professional and in-depth research on some problems existing in the market to provide convenience for everyone in future production applications.
Every time when spraying asphalt, the asphalt distributor does not spray asphalt. Troubleshooting. The asphalt distributor does not spray asphalt. It is a common fault. The following teaches you how to solve the problem of not spraying asphalt.
1. No asphalt spraying
Analysis of the reasons may be the following reasons:
1. Is the asphalt pump working?
2. Are the valves adjusted correctly?
3. Is the pump or pipeline blocked?
2. Troubleshooting method
1. Check whether the hydraulic system is working properly?
2. After adjusting the valve position, the asphalt distributor must be cleaned to avoid pipeline blockage when used next time. Because the asphalt distributor has different high and low configurations, it can spread various high-viscosity and high-temperature modified asphalts and rubber asphalt in high configuration. If you mistakenly use a low-configuration asphalt truck to spread this type of asphalt, you must spray the asphalt inside the entire vehicle clean after the first use. After spraying, in order to leave no residual asphalt, you can use waste diesel to clean it. Our company’s vehicles are equipped with air cleaning and gravity cleaning devices. Diesel cleaning is a reliable cleaning method.

In order to better play the role of slurry seal vehicles, this article explains the matters that should be noted from the aspects of the scope of application, type and material selection, construction technology, common diseases, etc. of slurry seal vehicles.
The slurry seal vehicle is thin in thickness and mainly plays the role of waterproofing, anti-skid, wear-resistant and improving the appearance of the road surface. In the pavement structure system, it can only serve as a surface protection layer and wear layer, but not a load-bearing structure. It is widely used in the construction and maintenance of highways. Practice has proved that the slurry seal can also play an important role by reasonably selecting the thickness and type of the slurry seal and strictly controlling the construction technology and quality.
(1). The scope of application of slurry seal vehicles includes the following aspects:
1. When the pavement damage index of expressways and first-class highways is evaluated as medium and below, or the pavement damage index of second-class and below highways is evaluated as secondary and below, when medium repair and overlay measures should be taken, slurry seal can be selected.
2. When the pavement driving quality index of expressways and first-class highways is evaluated as medium or below, or the pavement driving quality index of second-class and below highways is evaluated as second or below, medium repair and overlay measures should be taken to improve its flatness, and slurry seal can be selected.
3. For sections of expressways and first-class highways with insufficient anti-skid capacity (SFC<40), or sections of second-class and below highways with insufficient anti-skid capacity (SFC<33.5), measures such as adding overlays should be taken to provide anti-skid capacity of the road surface. 4. Anti-skid layer and waterproof protective layer used for third- and fourth-class highways to improve the appearance of the road surface.

Emulsified asphalt equipment plays an important role in road construction, and its production quality will directly affect the quality of facilities such as roads. In order to operate it better, we need to pay special attention to the following four points when applying emulsified asphalt equipment:
1. Before spraying, the emulsified asphalt equipment must check whether the position of each valve is correct. The hot asphalt added to the emulsified asphalt equipment must reach an operating temperature of 160~180℃. For long-distance transportation or long working time, a heating device can be used for insulation, but it cannot be used as an oil melting furnace.
2. When the asphalt in the emulsified asphalt equipment is heated by a burner, the asphalt height must exceed the upper plane of the combustion chamber, otherwise the combustion chamber will be burned.
3. The emulsified asphalt equipment cannot be filled too full, and the fuel filler cap must be closed tightly to prevent asphalt from overflowing during transportation.
4. This vehicle has two front and rear control consoles. When using the front control console, the switch must be turned to the front control. At this time, the rear control console can only control the lifting and lowering of the nozzle.
I believe that through the above description, everyone will be more comfortable when using emulsified asphalt equipment in the future. As for the relevant operating matters of the equipment, I will introduce them to you here today. If you want to know more information, please pay attention to the next explanation.

Emulsified asphalt is made by hot melting asphalt, dispersing it in an aqueous solution containing an emulsifier in a fine particle state through mechanical action, forming an oil-in-water asphalt emulsion. In road construction and maintenance projects, emulsified asphalt can be used for road maintenance, bonding between road layers, bridge deck paving, permeable oil on cement-stabilized macadam foundation, slurry seal waterproof layer, etc. It has the advantages of cold construction, safety, environmental protection, resource conservation, energy conservation, extended construction season, and improved construction conditions. It plays a very important role in the construction and maintenance of municipal roads, especially in recent years, the improvement of the production level of emulsified asphalt has actively promoted the technological progress and promotion and application of emulsified asphalt. However, in the production and use of emulsified asphalt, undesirable phenomena such as crusting, flocculation, oil-water stratification, and agglomeration often occur, which brings unnecessary troubles to construction. To this end, the author conducted a large number of experimental studies from nine aspects, including emulsification equipment, emulsifier, base asphalt, pH value, temperature, storage temperature, mechanical action, freezing and melting, and long-term placement, and summarized the factors that affect the stability of emulsified asphalt. The analysis is as follows:
