旧水泥混凝土路面上加铺沥青层时在面板接缝处及开裂处,加铺层容易产生反射裂缝。为了研究Sampave应力吸收层在重载路面结构中的防反射裂缝的效果,文章依托山西省夏家营—汾阳高速公路旧水泥混凝土路面加铺改造工程,详细介绍了Sampave应力吸收层特种沥青混合料在试验路段施工中的应用情况,对该技术的应用推广有一定的参考价值。 When adding asphalt layer on the old cement concrete pavement, cracks and crevices are easily generated in the joint and crevice of the panel. In order to study the effect of Sampave stress-absorbing layer on anti-reflective cracks in heavy-duty pavement structure, the article relies on the renovation project of old cement concrete pavement of Xiajiaying-Fenyang Expressway in Shanxi Province. The paper introduces in detail Sampave stress-absorbing layer special asphalt mixture Materials in the construction of the test section of the application of the technology to promote the application of a certain reference value.
