摘　　要：以昆明-安宁高速公路路面工程为实例，采用全寿命周期成本分析方法，对柔性基层长寿命沥青路面结构和传统强基薄面的半刚性基层沥青路面结构进行经济分析？分析表明，柔性基层长寿命沥青路面结构在分析周期内具有更低的直接成本，使用寿命可延长5～6倍，维修作业时间可缩短6～9倍，维修方便易行，对交通影响很小，可节约大量的用户间接费用.With the pavement project of Kunming-Anning Expressway for example, this paper adopts the total life cycle cost analysis method to make economical analysis for long-life asphalt pavement structure with flexible base and conventional asphalt pavement structure with strong foundation and thin surface and semi-rigid base. The analysis shows that the long-life asphalt pavement structure within the analysis cycle has lower direct cost, the service lifetime can be prolonged by 5 -6 times, and the maintenance time and be reduced by 6 - 9 times with convenience and very small impact on traffic, so a large quantity of indirect expenses can be saved for customers.
