| Abstract: | Using rutting test, soaked Marshall test and bending beam test at low temperature, the performances of compound additive modified asphalt mixtures with different gradations were studied. The research results indi- cate that the developed compound additive modified asphalt mixtures manifest des formance, crack resistance at low temperature and water stability, and can meet the ture composition for high volume traffic. rable high temperature per requirments of asphalt mixture composition for high volume traffic. |
