Non-Destructive Evaluation of Engineering Properties of Asphalt Mixtures
The measurement of dielectric response has gained importance because it can be used for non-destructive monitoring of asphalt pavements. The open-ended coaxial probe technique was selected to investigate the dielectric response of the dense-graded asphalt mixture. The effects of material properties such as density on dielectric response were examined. Results indicated that density have a significant influence on dielectric behavior of asphalt mixture. The dielectric constant was shown to increase with increasing density of the asphalt mixture, whereas a high density resulted in low voids that contributed to a relatively high dielectric constant. These findings could be used to enhance the accuracy of non-destructive electromagnetic devices applied in the pavement field.
