Method for Assessment of Modeling Quality for Asphalt Dielectric Constant to Density Calibration

Traditional measures of asphalt compaction rely primarily on random cores that only measure a small fraction of the pavement. Recently, the use of ground penetrating radar was indicated to be usable as a nondestructive means for the continuous assessment of asphalt compaction. A proposed Hoegh-Dai (HD) model has been successful in predicting air void content within typically achieved field compaction levels but has reduced accuracy at the...
