摘　　要：路面结构检测与评价是制定道路养护维修和改（扩）建计划的依据。采用路面状况指数PCI、路面综合破损率DR、结构能力指数SAI、路面强度系数SSI、路面构造深度TD、路面最大间隙h等指标，对旧沥青混凝土路面的破损状况、结构承载能力、抗滑性能、平整度进行评定；在以上检测与评价的基础上，结合不同类型旧沥青混凝土路面加铺层结构的经济性分析结论，推荐旧沥青混凝土路面加铺层典型结构方案，对于改进和提高改建工程项目设计、建设质量具有重要的指导作用和现实意义。The testing and evaluation in pavement structure is the basis of making plan for road maintenance and reconstruction. In this paper, by using of these indicators such as pavement condition index （PCI） , pavement damage ratio （DR）, structure adequacy index （SAI）, pavement strength coefficient （SSI）, pavement structure depth （TD） and pavement maximum gap （h）, the evaluation have been performed for the damaged condition, structural bearing capacity, skid resistance and smoothness of the old asphalt concrete pavement. Based on the tes- ting and evaluation results above, combined with the economical analysis conclusion of different overlay structures for old asphalt concrete pavement, the typical overlay structure for the old asphalt concrete pavement is recommen- ded, which plays an important role in improving the design and construction quality of the reconstruction project.
