30 This chapter describes the results of Phase 2 subcontract research conducted by Olson Engineering, Inc., at the National Center for Asphalt Technology (NCAT), Auburn University, in Alabama, and at test sites in Gainesville, Florida. The research examined nondestructive testing (NDT) and evaluation of the pavement at these sites with stress wave methods for debonded hot-mix asphalt (HMA) layers. The field portion of this investigation was performed in accordance with gen- erally accepted testing procedures. Research team members were Patrick K. Miller, Yajai Tinkey, and Larry D. Olson. Field testing of the Olson scanning IE/SASW system was carried out in Florida on a selected 0.4-mi section of I-75. The distance log was recorded as 0 to 2,167 ft. This chapter provides a graphical summary of the SASW results for each 50-ft length. The results are presented for incremental depths from 0.1 to 0.7 ft from the surface. The surface wave veloci- ties are shown by using a color scale, and higher velocities represent better pavement condition. Analysis of these data are reported in Volume 1. Figures 3.1 to 3.44 present various SASW test results. C h a p t e r 3 Olson Engineering, Inc., SASW Test Results from Florida Test Section
