| 摘 要： | 采用FWD对某高速公路旧沥青路面进行全线弯沉检测，以及对不同路面结构型式进行FWD与贝克曼梁弯沉比对试验检测，以分析评价旧沥青路面结构的强度状况。根据代表性路段旧沥青路面实测的结构层厚度和力学参数代表值，采用公路路面设计程序计算旧沥青路面顶面弯沉值，比较其与将FWD实测弯沉值转化为贝克曼梁弯沉代表值的差异，有益于旧沥青路面的弯沉检测。 |

| Abstract: | FWD is used to detect flexure of one expressway old asphalt pavement,and different types of pavement structures are tested through adopting FWD and Beckelman Beam so as to analyze and evaluate old asphalt pavement structure strength. According to representative sections of the old asphalt pavement structure of the measured layer thickness and mechanical parameters of the representative of value,highway pavement design procedures are adopted to calculate pavement surface flexure value. The value and the meas... |
