REHABILITATION STRATEGIES FOR HIGHWAY PAVEMENTS

This project was conducted to develop a process for selection of appropriate rehabilitation strategies for the ranges of pavement types and conditions found in the United States. A review of the pavement rehabilitation practices of State departments of transportation (DOTs), and the literature available on pavement evaluation, rehabilitation techniques, and selection of rehabilitation strategies, was conducted for this project. The rehabilitation strategy selection procedures used by the various state DOT agencies differ in their details, but typically consist of: (1) data collection, (2) pavement evaluation, (3) selection of rehabilitation techniques, (4) formation of rehabilitation strategies, (5) life-cycle cost analysis, and (6) selection of one pavement rehabilitation strategy from among the alternatives considered. This report provides a step-by-step process and guidelines for each of these activities.
