A Performance-Specified and Reliability-Based Approach for Life-Cycle Cost Analysis of Long Term Pavement Maintenance Contracts

摘要

The objectives of this paper are to present the feasibility of utilizing reliability-based method to quantify life-cycle cost associated with performance specification. And a framework develops for quantifying the life-cycle cost. The framework consists of three components: (1) the pavement deterioration performance prediction; (2) the reliability-based risk estimation; and (3) the life-cycle cost analysis. An example is illustrated using the International Roughness Index (IRI) data to demonstrate how the approach works. The approach has potential for use in valuation of long term pavement maintenance contracts.
