基于性能费用比的高速公路沥青路面基层选型

On selection of foundation of asphalt roadbed on expressways based on performance-cost ratio

在一定的交通、环境和经济条件下,为了合理有效地进行高速公路沥青路面基层类型的选择,综合考虑路面结构、材料、使用性能和路面费用,提出了性能费用比法,并进行了实例分析。研究结果表明该性能费用比法能够有效的用于高速公路沥青路面的基层选型。

Under certain traffic,environmental and economic conditions,the paper points out the performance-cost ratio by the comprehensive consideration over the roadbed structure,the materials,the utility performance and the roadbed cost to have the reasonable and efficient selection of the types of asphalt roadbed＇s foundation of the expressways,undertakes the example analysis,and proves by the research result that the performance-cost method can be applied in the foundation selection of the asphalt roadbed of expressway efficiently.
