摘要
本文针对不同结构类型的旧路面改造升级中的沥青罩面结构,建立了三维有限元计算模型,计算对比了半刚性基层路面结构清除旧路面层后加铺沥青层路面结构、旧沥青路面直接加铺沥青罩面结构、旧水泥路面直接加铺沥青罩面结构的力学响应的差异性,确定了三种不同结构的最不利应力及受力位置,并对可能引起的路面病害及防治措施提出了建议,可为以后旧路面改造升级沥青罩面结构选择提供技术指导与参考。
3D finite element model was builded for asphalt overlay structure of different structural types.The different mechanical response was contrasted for three structures of Semi-rigid base asphalt pavement、＂Black ＋ Black＂asphalt pavement、＂White＋ Black＂asphalt pavement.The most unfavorable stress and force location was determined for three structures,Recommendations were presented for possible road surface disease and preventive measures.Technical guidance and reference were provided for the future Asphalt overlay.
