Abstract

To study the influence of the mesh size of rubber powder in warm-mixed asphalt mixture and the warm-mixed agent on the low-temperature performance of rubber powder-modified asphalt mixture, the bending and bending creep tests of rubber powder-modified asphalt mixture with different mesh sizes before and after warm mixing were carried out. The results show that the low-temperature performance of the modified asphalt mixture with rubber powder is improved after warm mixing, and the low-temperature performance of the 60-mesh modified asphalt mixture with rubber powder is always better than that of the corresponding mixed mesh modified asphalt mixture with rubber powder. The combined bending failure energy density and temperature strain energy density can predict the cracking temperature of asphalt mixtures. The test results show that the low-temperature performance of the modified asphalt mixture with rubber powder has improved after warm mixing, and the low-temperature performance of the 60-mesh modified asphalt mixture with rubber powder after warm mixing is the best.
