Abstract
This TechBrief presents a general comparison of performance for rehabilitation strategies for flexible and rigid pavement. The impact of overlay thickness, preparation prior to overlay, and mix type on performance was statistically evaluated using data from the Long-Term Pavement Performance (LTPP) Specific Pavement Study (SPS)-5 and SPS-6 experiments. The document is a technical summary of the Federal Highway Administration report, Impact of Design Features on Pavement Response and Performance in Rehabilitated Flexible and Rigid Pavements (FHWA-HRT-10-066).
