| Abstract: | In the paper,significant findings and results from the experimental researches regarding the aggregate segregation test of asphalt mixture by using Ground-Penetrating Radar are as follows: the mutual relationship between the dielectric constant and density,percentage of voids and asphalt content of bituminous mixture and the correlation between density and the surface texture depth.The criterion for determining bituminous mixture segregation by GPR is obtained through the analysis of mutual relationship between the dielectric constant and gradation,density and percentage of voids of core samples. |

| Keywords: | ground penetrating radar(GPR) dielectric constant asphalt concrete pavement segregation |
