Cracks are common diseases of highways and asphalt pavements. A large amount of funds are spent on crack caulking in the country every year. In this case, it is particularly important to take corresponding treatment measures according to the actual road diseases and reduce maintenance costs.
For cracks, generally no treatment is required. If there are many cracks per unit area, surface sealing can be performed on them; for tiny cracks and small cracks, since they have not yet suffered structural damage, usually only a sealing cover is made on the surface, or the cracks are caulked and filled with caulking glue to seal the cracks.

The use of caulking glue is one of the most economical methods of road maintenance. It can effectively seal cracks, prevent the expansion of road cracks due to water penetration, and avoid causing more serious diseases, thereby slowing down the degradation of road use functions, preventing the rapid decline of the road condition index, and extending the service life of the road.
There are many types of potting glue on the market, and the materials and technical means used are slightly different. The potting glue developed and produced by Sinoroader is a road sealing material with heating construction. It is made of matrix asphalt, high molecular polymer, stabilizer, additives and other materials through special processing. This product has excellent adhesion, low temperature flexibility, thermal stability, water resistance, embedding resistance and aging resistance.
