摘要
利用MTS材料试验系统,进行旧水泥混凝土路面沥青加铺层弯拉型和剪切型反射裂缝的疲劳试验,评价了5种沥青加铺层结构抵抗反射裂缝的能力。结果表明,对于弯拉型疲劳试验和剪切型疲劳试验,普通沥青混凝土下面铺设STRATA应力吸收层、玻璃纤维格栅2种结构都具有良好的抗反射裂缝的能力,而在水泥混凝土面板上直接加铺沥青混凝土类结构的效果最差。
With material test system (MTS), the paper carried out fatigue test of flexural-tensile and shear reflection cracking of asphalt overlay on cement concrete pavement, evaluated the anti-cracking ability of five kinds of asphalt overlay structures. The results show that, for flexural-tensile fatigue test and shear fatigue test, the two kinds of structure of common asphalt concrete with STRATA stress absorbed layer and glass fiber grating had good ability to resist reflection cracking, while the effect of paving asphalt concrete directly on cement concrete slab was worse.
