Abstract:

In this research study, Spectral-Analysis-of-Surface-Waves (SASW), Falling Weight Deflectometer (FWD), and compression wave (P-wave) tests were employed at flexible pavement sites at the Texas Transportation Institute's (Texas A&M University) test facility in Bryan, Texas, at a newly constructed site on Loop 1 in Austin, Texas, and at pavement sites in Districts 1, 8, 11, and 21 in Texas. The objective was to improve field testing capabilities in relation to testing flexible pavement systems, and to compare SASW results with other in-situ techniques, including the FWD method. The elements primarily investigated included the selection and performance of high-frequency sources and receivers on asphalt concrete (AC) pavements, the effect of temperature and frequency on SASW and FWD measurements of AC pavements, and the effect of shallow depth to bedrock on the backcalculated moduli of the subgrade layer from each method.
