Abstract
A method for generating a calibration curve of asphalt concrete of a known mix. Initially, a single sample of the known asphalt concrete mix is obtained. The single sample has a known percent voids. A dielectric measurement of the single sample is obtained. Using only the dielectric measurement of the single sample, the sample's known percent voids, and a dielectric of air, a theoretical ideal dielectric for the asphalt concrete mix at 0% voids is computed. A dielectric vs. percent voids calibration curve is generated based on the computed ideal dielectric.
