    Abstract

    The spectral-analysis-of-surface-waves (SASW) method is a nondestructive method for determining elastic properties and thicknesses of pavement systems as well as natural soil deposits.

    This method consists of three phases: 1. Collecting data from field testing. 2. Converting these data to a dispersion curve. 3. Determining the shear wave velocity profile by inverting the dispersion curve.

    The computer program SASWOPR, developed at the University of Kentucky, performs the second of these three phases.

    SASWOPR is an easy-to-use interactive program that provides great flexibility to operate on field data in the process of generating a single dispersion curve (surface wave phase velocity versus frequency or wavelength). This graphics-oriented program is written in compiled BASIC and runs on a personal computer.
