半刚性基层沥青路面结构内部应变的现场测试与分析

Field Test and Analysis on Strain Sensors of Semi-rigid Base of Asphalt Pavement

为了能够获得实际车辆荷载作用下路面结构内部的力学响应,以G112国道工程为依托,结合我国半刚性基层沥青路面的设计经验,设计四种不同的路面结构形式,在沥青层和半刚性基层埋入应变传感器测量设备,通过不同的车辆荷载的作用,实现路面结构内部应变的测量,对半刚性基层沥青路面的结构性能和组合设计具有较大的参考价值。

To gain the mechanical response of the real pavement under vehicle loads, based on the experience in pavement design of our country, this paper designs four different structures supported by G112 project, embeds the strain sensors into surface layer and basic layer, realizes the field test and analysis on strain sensors of semi - rigid base of asphalt pavement under various vehicle load, and provides important basis for the design of the asphalt pavement.
