摘要
以广东省云罗高速公路耐久性沥青路面试验路为依托,通过对比改进型半刚性基层、碾压混凝土基层和倒装式半刚性基层三种沥青路面结构层间连续下的力学响应,应用国内外沥青路面设计方法预估三种沥青路面结构的疲劳性能.理论计算结果和4年跟踪试验观测结果表明,改性型半刚性基层和碾压混凝土基层沥青路面车辙深度小,使用性能好,疲劳性能优.
Based on the durable asphalt pavement test road of Yunluo Expressway in Guangdong Province,by comparing the mechanical response of three kinds of asphalt pavement structures with improved semi-rigid base,roller compacted concrete base and inverted semi-rigid base,the fatigue performances of three asphalt pavement structures are estimated in the methods of asphalt pavement design at home and abroad.The results of the theoretical calculation and the four-year follow-up of the test road show that the improved semi-rigid base and the roller compacted concrete pavement have small rutting depth,good performance and excellent fatigue performance.
