Performance Experiments on High-Modulus Asphalt Pavement of Long Steep Section

In allusion to the problem of increasingly serious forepart damage of long steep slope,especially the rutting,several kinds of asphalt mixture are designed to carry out the related mechanical properties test and the road performance test.The test results show that: two kinds of high module asphalt mixture′s resilient modulus and dynamic modulus value are higher than conventional asphalt mixture obviously.Through rutting test,freeze thawing split test and split test,the road performance of high module asphalt mixture is analyzed.The result shows that the high module asphalt mixture has good high-temperature stability and water stability performance.
