摘要

The focus of the study has been to evaluate the utility of seismic methods in the quality management of the hot mix asphalt layers. Procedures are presented to measure the target field moduli of hot mix asphalt (HMA) with laboratory seismic methods, conduct field tests with the Portable Seismic Pavement Analyzer (PSPA) in the field, validate the results in the laboratory with seismic tests on extracted cores and determine the design modulus from measured values. This report contains the results of an effort to address the issues related to the implementation of the recommended methods and devices in the day-to-day operation of the pavement community (in general) and pavements managed by the Arizona Department of Transportation (ADOT). Ten sites throughout Arizona with different pavement conditions and structures were tested between August and December 2005. The results are summarized in this report. Based on the results presented, the combination of the lab and field seismic methods is a viable tool for the quality management of HMA layers and can be easily implemented by ADOT.
