本文首先建立了土工布、玻璃纤维格栅、稀浆封层、同步碎石封层等4种柔性夹层及无夹层措施条件下的有限元模型,通过计算分析了半刚性基层裂缝损伤状态下行车荷载作用对各方案面层层底应力以及对柔性夹层材料的影响,最后通过室内裂缝轮碾模拟试验,评价了各柔性夹层抑制反射裂缝的作用。 In this paper, four kinds of flexible interlayers, including geotextile, glass fiber grating, slurry seal and synchronizing gravel seal, and the finite element model under the condition of no interlayer are established. By means of calculation, The effects of loading on the surface underlayer stress and the impact on the flexible sandwich material were studied. Finally, the effects of various flexible interlayers on reflex cracking were evaluated through the indoor cracked wheel rolling simulation test.
