Development of Performance-Based Evaluation Methods and Specifications for Roadside Maintenance

This report documents the work performed during Project 0-6387, "Performance Based Roadside Maintenance Specifications." Quality assurance methods and specifications for roadside performance-based maintenance contracts (PBMCs) were developed for potential use by TxDOT. These methods include a set of performance standards and timeliness requirements, a statistical condition assessment method for evaluating compliance with these performance standards, and a method for developing performance-based pay adjustment formulas. The developed performance standards, condition assessment method, and pay adjustment formulas were tested and refined using field trials. The field trials consisted of five 10-mi roadway segments located in TxDOT's Dallas, El Paso, San Antonio, Tyler, and Waco Districts. Finally, current practices in best-value bid evaluation methods for procuring PBMCs were identified and evaluated using simulation techniques.
