A new method of underpavement void detection that has potential for improving data interpretation has been developed. The effort was part of the Strategic Highway Research Program's effort to develop an experimental design to evaluate the effectiveness of the undersealing process. The Epoxy/core test will verify and calibrate the standard testing methods for finding voids. The test has been applied to 2 projects in Ohio. The test procedure entails the pouring of epoxy into the supposed void area through an access hole drilled in the pavement. A subsequent core reveals the presence of any hidden void. Three standard procedures are used to test voids: dynaflect, the falling weight deflectometer, and the static load. All 3 produce deflection data, interpretation of which indicates where undersealing would be appropriate. It is noted that the Epoxy/core test may halp in the interpretation and calibration of the data from these methods.
