基于沥青路面使用性能预估的全寿命周期内费用分析

Life Cycle Cost Analysis Based on Performance Prediction of Asphalt Pavement

摘要:

本文通过全寿命周期费用分析法，对五种沥青路面结构进行经济评价。通过分析发现：从初始修建费来看，柔性路面结构和组合式基层沥青路面结构高于国内常用的半刚性基层沥青路面结构，柔性路面结构初始修建费是国内常见半刚性基层沥青路面结构的2倍左右，组合式基层沥青路面结构是其1.5倍左右；从整个管理部门费用来看，半刚性基层路面结构管理部门费用高于柔性路面结构和组合式沥青路面结构，比柔性路面结构和组合式基层沥青路面结构高约20%~40%。研究结果表明，基于路面使用性能和全寿命周期内，组合式基层沥青路面结构管理部门费用和总费用均最优。

Abstract: In this paper, five kinds of asphalt pavement structures are economically evaluated through the full life cycle cost analysis method. Through analysis, it is found that from the initial construction cost, the flexible pavement structure and the combined base asphalt pavement structure are higher than the semi-rigid base asphalt pavement structure commonly used in China. The initial construction cost of the flexible pavement structure is the common semi-rigid base asphalt pavement structure in China. The ratio of the combined base asphalt pavement structure is about 1.5 times. From the perspective of the entire management department, the cost of the semi-rigid base pavement structure management department is higher than that of the flexible pavement structure and the combined asphalt pavement structure. The cost of the semi-rigid base pavement structure management department is about 20% - 40% higher than that of the flexible pavement structure and the combined base asphalt pavement structure. The research results show that the cost and total cost of the combined base asphalt pavement structure man-agement department are optimal based on the pavement performance and the whole life cycle.
