摘　　要：为准确分析旧路路面状况,合理优选改扩建加铺方案,依托内蒙古省际大通道工程,全面评价了旧路路面破坏状况,创新性地以行驶质量中的平稳颠簸情况来反映公路基层破坏状况,提出了以弯沉为主、旧路路面破坏状况和行驶质量指数为辅的旧路改扩建加铺标准并联合采用3D-Radar和钻芯取样的方法进行了验证与评价。该研究成果可为旧路综合评价和改扩建加铺提供理论依据。In order to accurately analyze the condition of the old road surface and rationally optimize the overlay scheme,the inter-provincial corridor project in Inner Mongolia was taken as an example.The damage condition of the old road surface was totally evaluated which was innovatively reflected by the stable and bumpy condition during driving;The standard of old road reconstruction was put forward,which was mainly based on bending and subsidence,old road pavement damage condition and partially based on driving quality indices;The test was verified and evaluated by 3D-Radar and core sampling.The research results can provide theoretical basis for the comprehensive evaluation and reconstruction of the old road.
