| Abstract: | The application effect of high modulus asphalt concrete additive calcium sulfate whisker in the asphalt mixtures is studied on the basis of road performance.Three mixtures are involved in the experiment and a comparative study of test results are carried out.The results show that the high modulus of asphalt mixture which is modified by calcium sulfate whisker can effectively improve the high temperature stability,water stability and anti-fatigue performance;at the same time,it doesn't decrease the mixture low temperature performance.Finally,the feasibility analysis shows that: the road performance of calcium whisker high modulus asphalt concrete pavement is good and it has high economic and social benefits. |
