Customized LCCA, a Practical Guide and Critical Tool: Case Study at TUS Airport

摘要

The Tucson Airport Authority (TAA) has developed an Airfield Safety Enhancement Program for Tucson International Airport (TUS) which includes the design of a new parallel Runway 12R/30L with new parallel and connector taxiways. Considering the vast scope for new pavement construction and ultimate cost implications, the development of an appropriate life-cycle cost analysis (LCCA) is a critical tool to evaluate and select viable pavement design alternatives. Following the Federal Aviation Administration guidelines, the LCCA was customized for project-specific conditions to closely represent the anticipated maintenance and rehabilitation measures across the 40-year analysis period. Utilizing the LCCA results, alternatives that involve a combination of flexible and rigid pavement systems are being designed for the project based on future pavement use, typical maintenance practices, and performance history of pavements at TUS. This customized and practical design approach provides a significant benefit to the airport and government agency when providing funding for the recommended pavement section.
