Asphalt repair agent is a commonly used pavement material with good waterproof and corrosion resistance. It consists of asphalt, asphalt, mineral fillers and additives, and is constructed on the road surface by spraying or coating to form a uniform and dense protective layer.

advantage

1. It can effectively prevent moisture penetration and improve the waterproof performance of the pavement. In rainy season or humid environments, asphalt can form a reliable barrier to prevent moisture from invading the pavement structure and extend the service life of the pavement.
2. Asphalt repair agent has good anti-ultraviolet ability. Ultraviolet rays are one of the main causes of pavement aging, which will harden and crack asphalt materials, resulting in road damage. Special ingredients added in asphalt can absorb and disperse ultraviolet rays, effectively delaying the speed of pavement aging.
3. Asphalt repair agent also has excellent wear resistance. During the vehicle's driving, the road surface will be subjected to friction and impact from the wheels, which will easily wear. The mineral filler in the asphalt mist seal can increase the hardness and wear resistance of the pavement, reduce wear and peeling, and improve the service life of the pavement.
4. Asphalt repair agents can also effectively prevent chemical erosion. The road surface is often exposed to various chemical substances, such as car exhaust, oil pollution, etc., which will cause corrosion and damage to the road surface. The asphalt mist seal can prevent the penetration of these chemicals and protect the pavement from damage.

Construction attention

First of all, we must ensure that the road surface is clean and dry. Only by constructing on dry road surfaces can the bonding performance of the asphalt mist seal be ensured. Secondly, the construction temperature must be controlled. Too low or too high construction temperature will affect the construction effect, and construction parameters need to be adjusted reasonably according to the temperature and road conditions.
Maintenance of asphalt repair agents is also important. Regular inspection and maintenance can promptly detect and repair road damage and extend the service life of asphalt repair agents. At the same time, avoid the use of chemicals or sharp objects that cause damage to the road surface.

In general, asphalt repair agent is a fully functional pavement protection material with many advantages such as waterproof, UV rays, wear resistance and chemical corrosion resistance. Through reasonable construction and regular maintenance, the service life of the road surface can be improved, repair and maintenance costs can be reduced, and traffic safety and comfort can be ensured.

Construction steps:

01. Clean the road surface
Before construction, the loose, peeled, cracked and the dust on the road must be cleaned (the road surface with oily stains must be thoroughly cleaned) to keep the road dry.

02. Paste the isolation tape
The construction area is pasted with tape to prevent contamination of other road surfaces and play a beautiful role. Pay attention to using tape to protect the markings in large areas.

03. Crack treatment
Before construction, the loose, peeled, cracked and the dust on the road must be cleaned (the road surface with oily stains must be thoroughly cleaned) to keep the road dry. If the road cracks are greater than 2 mm, glue is required.
04. Scrape or spray
Asphalt repair agent can be scraped and applied in small areas, while pressure sprayers can be used for large areas. The anti-slip microseal layer needs to be modified to the nozzle of the sprinkler truck, and agitating equipment is added, and it has continuous stirring ability to maintain uniform materials during construction. Manual scraping must have at least 2 scrapers (one front and one back) to ensure that the material is evenly distributed and penetrates into the asphalt pavement.

05. Open traffic
Traffic will be opened 4-5 hours after the construction of the asphalt repair agent, but when the temperature is slightly lower, the health time needs to be appropriately extended and traffic will be opened after the asphalt surface condenses.
The anti-slip microseal layer can be opened to traffic after 8 hours of completion (avoiding the vehicle turning around on the construction surface) and traffic can be opened normally in 24 hours.
