FIVE-INCH ASPHALT OVERLAY REHABILITATION. FINAL REPORT

This report is a case history study of the performance of a deep (five-inch) asphalt overlay over a portland cement concrete pavement. The study was intended to study the rate of reflective cracking on the overlay. After four years, approximately 25% of transverse joints had reflected through to the pavement surface indicating that all of the underlying transverse joints will have reflected through after 16 years of service. However, the pavement is already scheduled for resurfacing. Due to early rutting, which averaged 0.5 in. in the first three years, five miles of the southbound lanes were milled and resurfaced in 1988. The remaining is continuing to rut and will have to be resurfaced in the next several years. A second study entitled "Rehabilitation of a Rutted Asphalt Pavement" will continue this work and will evaluate the cause of the original rutting as well as evaluating the performance of the first rehabilitation project.
