• Description:
  This report describes the testing, construction, and 5 years of performance evaluations of a rehabilitated rutted asphalt pavement. The primary objective of this study was to investigate the effectiveness of a 2-in. high stability overlay topped with a plant-mixed seal coat (PMSC) in alleviating the rutting distress on I-25 north of Denver in Colorado. The following is a brief description of some of the findings: High-stability asphalt is not resistant to rutting, and rutting is returning to the rehabilitated southbound lanes, but at a slower rate than the standard mix. A preconstruction examination of the existing pavement indicated that the top mat makes the greatest contribution to the total rutting. The results of laboratory tests were largely inconclusive. No correlations were found between the measured rutting and pavement parameters such as stability, asphalt content, gradations, voids, etc.
