This report documents a detailed review of the Long Term Pavement Performance (LTPP) Special Pavements Study—5 (SPS-5) experiment. The purpose of the review was to determine the adequacy of the data provided by the experiment. The SPS-5 experiment, entitled Rehabilitation of Asphalt Concrete Pavements, is one of the key experiments of the LTPP program. Its goal is to develop improved methodologies and strategies for the rehabilitation of flexible pavements. The review concentrated on the core experimental test sections, with secondary emphasis on the supplemental test sections that were built by individual agencies for each SPS-5 project.

This report will be of interest to highway agency engineers involved in the collection, processing, and analysis of data that shed light on ways to improve on the design procedures andstandards for rehabilitating hot mix asphalt-surfaced pavements.
