Curling and Warping of Concrete Pavement: An Investigation and Proof of Concept Study
This project focuses on characterization of pavement behavior as it undergoes short-term curling and warping. Curling and warping cause slab deflections due to a temperature gradient and moisture gradient, respectively; this can result in excessive cracking and reduce the quality and lifetime of the pavement. In this study, one test section consisting of three panels was analyzed for early-age curling, warping, and shrinkage behavior. Deflection readings were taken on all three panels of the test section and one panel was instrumented with strain gages and moisture sensors. This procedure was a successful proof of concept in which we were able to determine that a relationship exists between strain, moisture, and deflection, indicating a relationship with curling and warping. Although data collected corresponds with the expected behavior, the amount of error produced from the test equipment and operators makes it difficult to accurately calculate deflection due to curling versus that due to warping
