LTPP Pavement Maintenance Materials: PCC Partial-Depth Spall Repair Experiment, Final Report
Highway agencies spend a large amount of time and money annually performing partial-depth spall repairs, both as temporary and permanent fixes. Frequently, the repairs are not made as efficiently as desired or do not perform as long as intended. The primary consequences are added disruption to traffic, more exposure of patching crews to traffic, and additional maintenance expenditures. The purpose of this study, then, was to address the merits and deficiencies of current spall repair materials, designs, and practices. The study evaluated the relative performance of selected patching materials, as well as the effect of selected repair methods. The study also examined repair material properties and tests that correlate well with field performance. This report documents the entire portland cement concrete (PCC) partial-depth spall repair study, including the installation of 30 unique repair type (i.e., combinations of patching material and patching method) at 4 different test sites, the laboratory testing of experimental repair materials, and the 7-year performance monitoring of the various partial-depth repairs.
