DEVELOPMENT OF A METHODOLOGY TO ESTIMATE PAVEMENT MAINTENANCE AND REPAIR COSTS FOR DIFFERENT RANGES OF PAVEMENT CONDITION INDEX

Abstract

This paper presents a network-level procedure for determining the best maintenance and repair alternative and its associated cost for different pavement categories at different Pavement Condition Index ranges. Data from a number of military installations in the United States were used, and the analysis was performed separately for each installation. The methodology developed included techniques for (a) Determining the fixed initial construction cost of each alternative based on local prices; (b) Determining the cost of pavement preparation before repair as a function of pavement type, condition, local prices, and installation policy for pavement preparation; (c) Determining the annual cost of routine maintenance of each maintenance and repair alternative as a function of pavement condition, local prices, and installation maintenance policy; (d) Determining pavement performance characteristics (service life and rate of serviceability deterioration) for various pavement categories; and (e) Conducting a life-cycle cost analysis of each alternative for all pavement categories at various Pavement Condition Index ranges using the equivalent uniform annual cost approach.
