The water stability research of the rubber powder-modified asphalt mixture

Abstract In recent years, research shows that crumb rubber modified asphalt can not only improve the pavement performance, but also reduce the pollution of waste tires. Therefore, based on the freeze-thaw test, the influence of hydrogen peroxide, rubber powder mesh number and rubber powder content on the stability of rubber modified asphalt mixture is studied. The results show that when the rubber powder content is 21% and the number of rubber powder mesh is 60, the rubber powder modified asphalt mixture has good stability, and hydrogen peroxide can improve the water stability of rubber powder modified asphalt mixture.
