Changing the color of asphalt pavement is an important project aimed at improving the beauty of roads, optimizing traffic signs and enhancing urban landscape effects. The following is a detailed introduction to the color change of asphalt pavement:
1. Color change method
Using pavement color change spray:
Spray directly on the original asphalt pavement surface to make the road surface look brand new.
This method is simple and fast to construct, with bright and lasting colors, and will not change the structure of the pavement.

Using colored asphalt technology for paving:
Paving a layer of colored asphalt surface with a thickness of 3~5cm, which is both beautiful and durable.
This method requires professional construction equipment and technology, but the color change effect is long-lasting and is suitable for occasions with high requirements for road performance.

Using colored anti-skid particles for paving:
First pour a layer of anti-skid glue on the road surface, and then sprinkle colored anti-skid particles.
This method not only increases the beauty of the road, but also improves driving safety, especially for occasions that require anti-skid treatment.

2. Color change steps
Preliminary preparation:
Carry out a comprehensive inspection of the original asphalt pavement to ensure that its surface is flat and undamaged, and there are no looseness, cracks and other defects.
If there are quality problems, it is necessary to repair it first to ensure that the color-changing paint can bond well with the base layer.

Cleaning the pavement:
Use a pavement dry cleaner to clean the dust on the original asphalt surface layer, and clean it with water if necessary.
Ensure that the pavement is clean and tidy, providing a good foundation for subsequent color change construction.

Spraying the interface layer:
Use a special primer to spray a construction interface layer on the working surface.
During the construction process, ensure that the foundation is not contaminated, and proceed to the next step of construction after the surface is dry.

Spraying the color layer:
After the interface layer is dry, use an airless sprayer to spray the colored water-based pavement anti-skid paint.
Both sides of the pavement and roadbed should be protected with adhesive tape and plastic film to prevent pollution.

Spraying the protective layer:
To ensure that the finished colored surface layer is bright and lasting, a layer of transparent hydrophobic topcoat can be sprayed after the colored surface layer is sprayed and cured.
This layer of protective agent can effectively improve the aging resistance of colored pavement.

3. Precautions
Material selection:
The color-changing paint should use special colored pavement paint, which is not only bright and long-lasting, but also has good weather resistance, wear resistance and adhesion.

Color design:
The color selection of the pavement color change should consider functionality and aesthetics.
For example, different colors can be used to distinguish the lanes, sidewalks, bus lanes, etc.; at the same time, it should comply with the relevant national regulations on road traffic signs and markings.

Construction process:
Strictly follow the construction process of colored pavement paint.
Including base surface cleaning, primer brushing, color paint coating, surface layer protection and other steps, and ensure that each layer of paint is completely dry before proceeding to the next process.

Environmental protection:
Pay attention to environmental protection during construction to prevent paint from polluting the surrounding environment.
At the same time, the paint itself should have low VOC (volatile organic compounds) characteristics to reduce the impact on air quality.

Safety protection:
Obvious warning signs should be set up at the construction site to ensure the safety of pedestrians and vehicles.
Construction workers need to wear protective equipment to avoid direct contact with chemical paint.

Post-maintenance:
After the color change is completed, regular inspections should be carried out to promptly discover and repair problems such as coating shedding and wear.
To extend the service life of the colored pavement.
In summary, the color change of asphalt pavement is a complex and meticulous project that requires a professional construction team and high-quality color change materials to ensure the color change effect and quality.

    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.

    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.

    The viscosity of emulsified asphalt equipment decreases with the increase of temperature during the production process. The power viscosity of emulsified asphalt equipment is about twice as high as every 12℃ increase. During processing, the culture medium asphalt barrel should be heated to liquid before demulsification. In order to better integrate the demulsification emulsified asphalt equipment capacity of the colloid solution mill, the culture medium asphalt barrel power viscosity is generally controlled to be about 200cst. The lower the temperature, the higher the viscosity, which increases the pressure of the asphalt barrel pump and the colloid solution mill, and the emulsion cannot be demulsified. However, on the other hand, in order to prevent the emulsified asphalt equipment from weaning when the finished product water evaporates, it is unlikely to overheat the culture medium asphalt barrel temperature. Generally, the finished product temperature at the inlet and outlet of the colloid solution mill should be less than 85℃.
    One of the important methods to control the temperature and viscosity of emulsified asphalt equipment during processing is based on this. Everyone must carry out scientific operation according to the instructions of the emulsified asphalt equipment, so that the characteristics of the emulsified asphalt equipment can be fully presented. The development trend of the drying theory of emulsified asphalt equipment requires the stone resources to be processed, dried and heated. The reason for the emulsified asphalt equipment is that the quality of wet raw materials does not meet the requirements of asphalt mixture production and processing technology equipment companies.
