摘要
目前国内外道路工程界对用于防止旧水泥混凝土路面沥青加铺层反射裂缝结构和材料的研究仍处于探索与试验阶段。本文采用M TS模拟水泥混凝土板沥青加铺层弯拉型和剪切型反射裂缝扩展过程,评价不同防裂材料的阻裂效果,为优选沥青加铺层结构提供依据。
Currently, the researches of road engineering on the structures and materials of antireflective cracking of asphalt concrete overlays on concrete pavement are still in an early stage of explorations and trials. The MTS is applied to simulate the propagating process of reflective cracking of bending styles and shearing styles in asphalt overlays, the anti-cracking effects of different kinds of anticracking materials are evaluated, the experiments offer a basis to choose the optimal overlay structures.
