In highway construction, due to the excellent driving comfort and performance of asphalt pavement, as well as its fast construction speed and convenient maintenance, asphalt materials have become one of the most important building materials for highway pavements. Asphalt has strong plasticity and load-bearing capacity, which can ensure safer vehicle operation and reduce noise generated by friction with the ground. In today's article, the editor of Qingdao Sainuo will introduce the application of Sainuo's two major additives - OPE wax and EBS - in asphalt.

Adding EBS wax to asphalt can reduce its viscosity, improve its softening point, water resistance, and weather resistance. Asphalt with a good softening point can maintain stability in high-temperature environments and is not easily softened, thus ensuring the smoothness and safety of the road. In addition, the asphalt with high softening point can also improve the whiteness and anti-aging performance of the pavement and extend the service life of the road.

OPE 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, improve asphalt components, and do not need to worry about precipitation from asphalt when the state changes. It can quickly and uniformly melt and disperse during the asphalt mixing process, improve the viscosity of asphalt, and enhance its ability to resist flow, Significantly improve the rutting resistance of asphalt mixtures while meeting other performance requirements of asphalt mixtures.

Compared with the original asphalt, the asphalt modified with oxidized polyethylene wax has significantly improved and improved high-temperature performance, elongation, stretching, elasticity, and compatibility with the mixture; It can effectively improve the storage stability of modified asphalt, reduce the occurrence of segregation, and maximize the low-temperature ductility of modified asphalt, improve high-temperature resistance to rutting and low-temperature resistance to brittle cracking, making it suitable for use in high-temperature and low-temperature areas.

Experimental data shows that when the content of oxidized polyethylene wax modifier increases from 0 to 20%, the softening point of asphalt increases, the penetration decreases, the low-temperature ductility increases, the expansion and contraction performance improves, and the elastic recovery improves. The effect is very significant, and the high and low temperature performance is significantly improved. Therefore, as an asphalt modifier, oxidized polyethylene wax has a large dosage and good market prospects.

Oxidized polyethylene wax as an asphalt modifier meets the technical requirements of the transportation industry standard of the People's Republic of China "Asphalt Mixture Modification Additives (JT/T 860.1-2013)".
