The application of oxidized polyethylene wax in asphalt modification. The developed countries have started to use oxidized polyethylene wax modifier in road asphalt, and have achieved good application results. It is hoped that asphalt roads will not be deformed in summer and cracked in winter, that is, they will have good rutting resistance at high temperatures, and also have high cracking resistance at low temperatures.

Oxidized polyethylene wax has excellent cold resistance, heat resistance and wear resistance, good chemical stability and good compatibility with asphalt. As an asphalt modifier, it can quickly combine with asphalt and improve asphalt components, without worrying about the separation from asphalt when the state changes. It can quickly and uniformly melt and disperse during asphalt mixing, improve the viscosity of asphalt, and improve the resistance of asphalt to flow, Significantly improve the rutting resistance of asphalt mixture.

At the same time, it meets other performance requirements of asphalt mixture. Compared with the original asphalt, the asphalt modified with oxidized polyethylene wax has high temperature performance, elongation, tension, elasticity, compatibility with the mixture, anti-aging performance, etc. It has obvious improvement; It can effectively improve the storage stability of the modified asphalt, reduce the occurrence of segregation, increase the low-temperature ductility of the modified asphalt, improve the high-temperature rutting resistance and low-temperature brittleness resistance, and is suitable for use in high-temperature and low-temperature areas.
