长大纵坡路段高模量沥青路面性能试验研究

针对长大纵坡路段早期损坏现象日益严重,特别是车辙病害突出的问题,通过设计几种不同的沥青混合料进行相关的力学性能测试与路用性能试验发现：高模量沥青混合料的回弹模量和动态模量值都有显著提高;通过车辙试验、冻融劈裂试验、劈裂试验,分析了高模量沥青混合料的路用性能。试验结果表明高模量沥青混合料具有良好的高温抗车辙性能与水稳定性能。

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.
