以上海市罗山路工程为依托 ,在施工阶段逐层进行了测定 ,包括回弹弯沉、承载板测定路面当量回弹模量、各结构层底面应变状态等。通过测定数据的分析 ,研究半刚性基层沥青路面各结构层的贡献情况 ,对分析半刚性基层沥青路面结构的结构性能 ,进行路面结构的组合设计具有较大的参考价值
Based on the Luoshan Road project in Shanghai Municipality, the measurement was carried out layer by layer during the construction phase, including rebound deflection, the equivalent modulus of resilience of the pallet and the strain of the bottom of each structural layer. Through the analysis of measurement data, the contribution of each structural layer of semi-rigid asphalt pavement is studied. It has great reference value for analyzing the structural performance of semi-rigid asphalt pavement structure and combining design of pavement structure
