This project was funded under the FHWA Federal Lands Highway Technology Deployment Initiatives and Partnership Program (TDIPP).The focus of the study was to evaluate the effectiveness of the Portable Seismic Property Analyzer (PSPA) to rapidly and nondestructively measure thickness and in situ moduli of asphalt pavement layers. These procedures are presented to calibrate and validate the results in the laboratory with simplified seismic tests on extracted cores and determine the design modulus from measured values. Performing these simplified laboratory and field tests along with more traditional tests may result in a database that can be used to smoothly unify the design procedures with pavement evaluation. Specifically, six sites with different pavement conditions and structures throughout Colorado were tested October 2003, and the results summarized in this report. Based on the results, the PSPA is proposed as a viable tool for immediate implemetation by the Federal Highway Administration, Federal Lands Highway.96
