以广东省某高速公路长陡坡路段为依托,通过采用高模量改性沥青、纤维加强及掺加界面添加剂等方式改进沥青混合料的抗车辙能力,并以此为基础设计了5种路面结构。通过有限元方法对这些路面结构在高温条件下的性能进行了力学分析,为拟定试验段路面结构方案提供理论依据。
Based on the long steep slope section of a highway in Guangdong Province, the anti-rutting ability of asphalt mixture was improved by using high modulus modified asphalt, fiber reinforced and interfacial additives. Based on this, five kinds of pavement structures . The mechanical properties of these pavement structures under high temperature conditions were analyzed by finite element method, which provided theoretical basis for formulating the pavement structure scheme in the test section.
