Experimental Study on Dielectric Properties of Pavement Structure Layer Based on Radar Image

Abstract

This paper aims to study the dielectric properties of pavement structural layer by using radar images. Asphalt cement mixture was taken as a case study to analyze the dielectric properties of the pavement structure layer material. The results show that it has been found through research that there is a close relationship between the dielectric properties of the pavement structure layer material and the gross volume, and the value of the dielectric constant may be affected by changes in the relative density of the hair volume. Therefore, the radar image has a certain applied research value in the dielectric properties of the pavement structure layer materials, and it is worthy of reference of relevant parties.
