This project will study the feasibility of measuring slab curvature using a non-contact, high-speed profiler system assessed by the Pavement Surface Analysis Laboratory (PSAL) of the Turner-Fairbanks Highway Center of the Federal Highway Administration (FHWA). The objectives of this study were to: (1) measure the curvature of concrete slabs using existing profiling technology; (2) establish a standard procedure to identify warp and curl from profiler data; (3) quantify the change in curvature due to temperature changes; (4) determine the sampling interval required to measure curvature; (5) determine the relationship between curvature and roughness measurements; and (6) relate curvature data to premature transverse pavement cracking and construction conditions.
