Investigation of Spall Repair for Concrete Pavement
This report summarizes the research results obtained from laboratory and field tests of spall repair materials. Repair materials tested included cement-based ready-mix materials, polymer-based materials, and concrete containing accelerating admixtures. Tests were conducted to measure time of setting, compressive and flexural strengths, fracture toughness, and bond shear strength between repair material and base concrete. These tests can be used to characterize spall repair materials. Researchers found that properties of the repair materials depend on the age and environmental factors. Spall repairs with these materials on concrete pavement were evaluated in the Houston area. Performance of repair patches depends on the strength, especially bond strength, developed at the time when the repaired road is open to traffic.
