| Abstract: | In order to improve the pavement performance of asphalt mixture, rubber powder is added to the matrix asphalt to realize the compound modification. The technical indicators of the performance of the rubber-modified asphalt are tested, with the mechanism of the rubber powder and asphalt analyzed. Through laboratory tests, the rutting tests, the low-temperature bending tests,and the remaining stability tests of the rubber-modified asphalt mixture, and comparing the residual matrix asphalt with the SBS modified asphalt mixture, to test the stability performance of the rubber modified asphalt mixture at both high temperature and low temperature and its resistance to water damage. Our research shows that the effect of the rubber modified asphalt mixture is remarkable. |
