Evaluation of Asphalt Pavement Using Ground Penetration Radar


This paper presents a status report on evaluation of the asphalt pavement using the ground penetration radar device (GPR) in one of the University of Technology streets about 92 m length. The technique of GPR is a nondestructive geophysical method that gives information about the thickness of asphalt pavement layers, existence of drainage pipes, rutting places and produces a continuous cross-sectional profile or record of subsurface features without drilling, probing, or digging.Three samples of asphalt were taken from different places of the street. The thickness of asphalt layers were measured from these samples. One of the samples consists of two layers and the others of one layer.Comparison of the two results of the thickness from the device and the sample indicate that there was very slight difference between them.
