Asphalt road sealant is primarily composed of a composite material of modified asphalt and thermoplastic rubber. Its key performance characteristics are low viscosity at high temperatures and high elasticity at low temperatures. Replacing traditional asphalt crack caulking with sealant for treating asphalt pavement cracks represents a significant advancement in current highway maintenance technology. Traditional methods are limited by asphalt's low-temperature brittleness and high-temperature softening properties, resulting in cracks quickly reopening after repair. This problem increases the labor and material costs of pavement maintenance. However, sealant crack caulking overcomes these shortcomings in terms of material performance.

Asphalt cold patch material is a high-viscosity, fast-setting, waterproof, high-quality product. It has excellent marking properties in the field of road maintenance. Our asphalt cold patch material is not affected by seasonal, regional and other conditions. It is easy to construct and has a long service life.
