Abstract

This technical memorandum summarizes the analysis performed in evaluating Long-Life Pavement Rehabilitation Strategies (LLPRS) cost. This study is part of the effort to develop an Integrated Pavement Strategy Decision Support System to allow engineers to analyze efficient allocation of financial resources when planning pavement projects.

This study analyzed cost performances of a long-life pavement project on Interstate 80 between Nevada County (Truckee) from east of the Fireboard undercrossing to the west end of the Truckee River Bridge.

The rehabilitation project involved rehabilitation of an 11-mile stretch of I-80 (approximately 46 lane miles) between West Boca and Floriston, east of Truckee. The contract was awarded to Granite Construction Company of Watsonville; construction began April 2, 2001. The cost of the project was estimated to be $88 million, however, the final cost of the project totaled at about $99 million. The analysis performed determines the reasons for the difference between the estimated and actual costs.
