Evaluation of Concrete Pavement Conditions and Design Features Using LTPP FWD Deflection Data

---

The Long Term Pavement Performance (LTPP) study uses Falling Weight Deflectometers (FWDs) to collect deflection data. As part of a study sponsored by the Federal Highway Administration, load transfer efficiencies (LTEs) were calculated for all the test points of each section of the LTPP GPS 3, 4, and 5 experiments. From statistical analysis, it was found that the doweled joints have significantly higher LTEs than the non-doweled joints. Voids at the slab joints and corners were computed by examining the deflection data of the joint and corner tests at different load levels. The loss of support was then expressed as the percentage of joints or slab corners with voids for each LTPP concrete pavement test section. By examining the ratio of the maximum deflection at the mid-slab test location versus the edge locations, the concrete shoulders were found to provide significantly greater edge support than asphalt shoulders based on a one-tailed Student t-test.
