试论全寿命分析法在路面设计中的应用

Discuss on the application of total life analysis in pavement design

全寿命设计方法是一项较新的设计理念,将其用于路面设计目前为止还不多。讨论了美国相关法案(Pave- ment Division Interim Technical Bulletin)中的路面全寿命分析(LCCA)方法,并基于该思路提出了路面全寿命设计方法,试图建立全寿命路面设计的初步体系。

Total life analysis is a new kind of analysis method,but it is unusually used in pavement design.This paper firstly discussed Life-cycle cost analysis(LCCA)in pave- ment design from Pavement Division Interim Technical Bulletin in U.S..Then the total life pavement design method based on LCCA has been proposed.And some efforts are also made to build a system of total life analysis in pavement design.
