EVALUATION OF MASW DATA TESTING CONFIGURATION FOR ANALYSIS OF ASPHALT PAVEMENTS

The development of multi‐channel surface waves (MASW) analysis in recent years is promising for accurate non‐destructive characterization of asphalt (HMA) pavements. This paper investigates the application of MASW to pavements in order to characterize the effects of testing configuration, material temperature and pavement structure on the results. Experimental results from full‐scale composite section and full‐depth HMA pavements are reported for a wide range of material temperatures. The results show that these parameters affect MASW response behavior, and this data interpretation and accuracy.
