摘　　要：采用全寿命周期成本经济分析(Life-Cycle-Cost-Analysis,简称LCCA)法对昆安高速公路第十三合同段优化前的半刚性沥青路面和优化后的柔性基层沥青路面这两种路面结构分别进行了全寿命经济性能分析,分析结果表明:柔性基层沥青路面结构的全寿命周期成本与成本-效益指标均大大优于传统的半刚性基层沥青路面结构,值得广泛推广。This paper introduced the method and connotation characteristics of life - cycle cost analysis of the economy （ Life - Cycle - Cost - Analysis, referred to as LCCA）, and the method used for Kun highway optimized the 13th paragraph of the contract prior to the semi - rigid asphalt pavement Optimized -- an and flexible base asphalt pavement structure.of the two roads were carried out life - cycle net present value and life cycle cost - benefit analysis method of analysis , the results showed that： Flexible of the whole life - cycle costs and cost - effective indicators are significantly better asphalt pavement structure. Asphalt Pavement structure than traditional semi -rigid
