Evaluation of Moduli and Thicknesses of Pavement Systems by Spectral-Analysis-of-Surface-Waves Method
The Spectral-Analysis-of-Surface-Waves (SASW) method is a nondestructive method for evaluating the moduli and thicknesses of pavement systems. By means of a transient impact applied to the surface of a pavement system or soil deposit, a group of waves with different frequency components is transmitted to the medium. By analysis of the phase information for each frequency determined between two receivers located on the surface, Rayleigh wave velocity, shear wave velocity, and eventually elastic moduli and thicknesses of the various layers in the pavement system are determined. The method has the advantages of being: (1) fast and economical, (2) nondestructive, and (3) capable of full automation. Three series of tests were performed on State Highway 71 near Columbus, Texas. These tests were performed on a continuously reinforced concrete pavement, an asphaltic-concrete shoulder, and a soil median.
