The report describes a three phase field investigation of shallow seismic techniques to determine their application to highway problems. Phase 1 was an evaluation of wave sources, wave detectors and seismic instruments. Phase 2 was a study of refracted compressional waves, reflected waves, uphole waves, surface waves and shear waves. Phase 3 was an evaluation of the accuracy of predictions based on seismic information. A study of refracted and uphole velocities indicated the refracted velocities gave a better indication of the physical properties of a material. Shear waves were collected and used to determine dynamic moduli of the materials. Reflections could not be obtained at most of the test sites because of interference from shallow refractions.
