摘要
针对传统的半刚性基层沥青路面在广东高温、多雨、重载条件下耐久性不足的问题,尝试采用碾压混凝土基层沥青路面提高路面的耐久性能。对两种碾压混凝土基层沥青路面结构进行了力学响应分析,并对其疲劳寿命和车辙深度进行预估,结果表明两种路面结构均可满足重载交通的要求;该路面结构在广东云罗高速公路全线采用,通车3年后,路面使用性能优良。
In view of the problems of the traditional semi-rigid base asphalt pavement in Guang dong high temperature,wet and heavy load conditions,roller compacted base for pavement has been adopted to improve pavement durability. In this paper,mechanical response analysis of two kinds of asphalt pavement structure have been carried out,the fatigue life and rut depth have been predicted. The results have shown that both of the two kinds of pavement structure can meet the requirements of heavy traffic; the pavement structure,being used in Guangdong Yunluo Expressway,has achieved excellent performance after 3 years of operation.
