中文摘要：

为了研究高温与长期荷载条件下聚酯布对沥青路面抗车辙性能的影响,选择两种聚酯布进行车辙与MMLS3试验,并结合时-温等效理论分析两个试验结果的相关性。车辙试验结果表明与普通试件相比,高温条件下1#、2#聚酯布试件的车辙深度依次降低24.7%和55.7%,动稳定度分别提高1.8和2.5倍。MMLS3试验结果表明长期荷载作用下聚酯布试件的最终车辙深度比普通试件小约20%;25万次加载后普通试件出现剪切裂缝,进入破坏阶段,聚酯布试件则进入稳定剪切变形阶段。两个试验共同说明高温与长期荷载条件下,聚酯布均能有效分散轮胎荷载应力,提高沥青路面的抗车辙性能。

英文摘要：

In order to study the impact of polyester paving mat on the anti-rutting performance of asphalt pavements under high-temperature and long-term loads, 2 kinds of polyester paving mat are selected to conduct rutting test and MMLS3 test, and the correlation between the 2 test results is analyzed by time- temperature equivalence theory. The rutting test result shows that the rutting depth of the 1st and the 2nd polyester paving mat specimens are reduced by 24.7% and 55.7% respectively, and the dynamic stability are increased by 1. 8 and 2.5 times at high-temperature compared with the control specimens. The MMLS3 test result shows that （1） the final rutting depth of mat specimens is about 20% smaller than that of the control specimen under long-term loads; （2） after 250 000 times loading, the control specimens appeared shear cracks and entered into damage phases; while the polyester paving mat ones stepped into steady shear deformation phase. The 2 tests indicates that polyester paving mat can effectively disperse tire load stress and improve the anti-rutting performance of asphalt pavement under high-temperature and long-term loads.
