| Abstract: | The article selects the different base asphalts and analyzes the influence of the rock asphalt on the performance of the asphalt mixture and the optimized dosage of the rock asphalt. According to the related measured indexes, the article analyzes and discusses the influence and level of rock asphalt as the modifying agent on the base asphalt from the high temperature performance, the low temperature and durability performances. The results indicate that the high temperature performance of the asphalt is enh... |
