Product Features of Asphalt Modifier:
1. High temperature, strong resistance to rutting
Asphalt modifier containing natural bitumen softening point is very high, generally in the 160 ~ 175 °C, so the use of its manufacturing of asphalt softening point also improved significantly, the modified asphalt has excellent high temperature performance, can significantly improve the pavement rutting resistance.
2. High nitrogen content, and strong resistance to water damage
Asphalt modifier containing a high nitrogen content of natural asphalt, bitumen up to several times higher than normal, and nitrogen to form functional groups, which form in the asphalt viscosity, oxidation resistance increased, especially and aggregate adhesion and anti-stripping has been significantly improved. And organic amine anti-stripping agent compared to the resistance to water damage to the ability to more stable and durable.
3. Anti-aging ability
Asphalt coexist with the natural environment all year round, particularly stable nature, has a strong anti-microbial erosion, and in light of the free surface to form dense protective film. Adding natural rock asphalt can greatly improve the ability of ordinary asphalt UV, which will improve the durability of asphalt pavement, asphalt slow down the aging rate, thus prolonging the life of the road.
