• Abstract:
  After the successful experimentation in Iowa with thin-bonded concrete overlays as an alternative to bituminous overlay, the Louisiana DOTD decided to resurface a short section of US 61, north of Baton Rouge, using this technique during April 1981. The resurfacing consisted of 5.8-bag, limestone aggregate concrete mix with an average thickness of approximately 4 inches. ; The overlay increased the serviceability index of the pavement from 2.3 to 4.0 and increased the skid resistance from 36 to 64. ; Four months after construction, in August 1981, some disbonding was experienced on slabs adjacent to pressure relief joints which had closed more than anticipated. A high modulus epoxy-resin was used to rejoin the concrete resurfacing at these locations. Additionally, approximately 10 percent of the exterior slab corners appear to have experienced varying degrees of disbondment. After 11 months of service, the disbonded corners have not resulted in any slab cracking or other distress related problems.
