Study of Materials to Inhibit Reflective Cracking in Asphalt Overlay Placed Over CRC Pavement
The South Carolina Department of Highways and Public Transportation has a large investment in continuously reinforced concrete (CRC) pavements. Adequate rehabilitation of CRC pavements to protect the major investment is vital. A rehabilitation technique used on a section of I-95 in Dillon County was to remove severely distressed portions of the pavement, replace with partial or full depth concrete patches, and overlay with asphaltic concrete. There was concern that cracks in the CRC pavement might reflect through the overlay. The study was initiated to determine if reflective cracking was a problem and to evaluate the effectiveness of several different methods of inhibiting reflective cracking. The cracks typical of CRC pavement did not present a problem in any of the test or control sections. However, reflective cracks were noted in the overlay at the boundaries of patches placed in the CRC pavement. None of the reflective crack inhibiting methods or materials used were judged to be effective in reducing or retarding these cracks.
