CASE STUDIES IN REHABILITATION STRATEGY DEVELOPMENT

Restoration is a rehabilitation strategy that involves a combination of repair methods. It is sown that it is possible to assess the appropriateness of restoration using information available about the design and condition of a particular pavement section, rehabilitation performance prediction models, and rehabilitation cost data. The paper shows how this can be done using the EXPEAR computer program to compare rehabilitation strategies for 13 pavement projects from across the United States, and representing a wide range of pavement conditions. EXPEAR is intended for use in rehabilitation planning and design for high-volume, conventional concrete pavements. The evaluation procedure is described for 'good condition,' 'fair condition,' and 'poor condition' sections.
