PAVEMENT ECONOMIC ANALYSIS MADE EASIER

This paper describe a microcomputer program, PRLEAM, developed for project level life-cycle economic evaluation of pavement rehabilitation alternatives. It provides a general outline of the methodology for conducting pavement life-cycle analysis, as well as an example of program operation. PRLEAM uses the present worth method of analysis. It combines four sets of costs (related to construction, maintenance, user delay during construction, and salvage value) together with the corresponding economic benefits. Economic benefits are calculated using the effectiveness method which reflects pavement performance, section length, and traffic volume. The program is user friendly and the work is guided through self-explanaotry menus. It provides quantitative support to pavement designers for selecting appropriate project-specific pavement rehabilitation treatments.
