• Abstract:
  The most common method used to rehabilitate existing portland cement concrete (PCC) pavements is to place an overlay consisting of asphalt concrete. However, problems with premature rutting of the asphalt overlay and early appearance of reflective cracks in the asphalt overlay have made overlays consisting of portland cement concrete a viable alternative rehabilitation method. Most PCC overlay failures can be attributed to causes other than improper overlay thickness, suggesting that existing design procedures such as the AASHTO procedure provide sufficient overlay thickness to satisfy design requirements. In this study, major factors affecting overlay performance were identified; guidelines for considering those factors in design are presented. In addition, user-friendly computer spreadsheets were developed to aid designers in completing AASHTO-based thickness design for unbonded and bonded PCC overlays.
