Thin Bonded PCC Resurfacing
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 U.S. 61, north of Baton Rouge, using this technique during April 1981. The resurfacing consisted of 5.8-bag, limestone aggregate concrete mix with a minimum thickness of 3 inches. The new overlay increased the serviceability index of the pavement from 2.3 to 4.0 and increased the skid resistance from 36 to 62. Approximately 16 percent of the exterior slab corners have experienced varying degrees of disbondment, resulting in a minor degree of cracking. Deflection measurements indicate that the overlay has maintained much of its initial gain in structural capacity. Recommendations are made relative to construction of future thin-bonded PCC overlays.
