The road in Malaysia has been growing rapidly in recent times and has become the main transport route for goods and people. This has resulted in the increasing in economic activity leading to greater tonnage being transported by road. This is further assisted by the increase of the road network by building new highways and increasing the traffic capacity of the existing highways / roads. It is necessary to properly design the standard of the roads and the thickness of each layer to compensate for this increased traffic movement and the tonnage too. More precisely, GPR assists in the quality assessment and interpretation of pavement conditions. The pavements tend to have problems with the use, such as cracking, roughness, rutting and raveling over a period. To enhance the life of pavement, improve its riding quality, and minimize the maintenance requires thorough investigations of the existing pavements. In this project, visual assessment also has been used on 200 m of selected road in Universiti Tenaga Nasional (UNITEN). The methods used conventionally are time consuming, difficult to perform, and not economical. So geophysical method such as ground-penetrating radar (GPR) is an alternative to the conventional methods, and being nondestructive, it is less difficult, time consuming, and also economical to use which gives detailed information about the pavement layer thickness and image of GPR produce the image of underground pavement that cannot be seen. Thus, GPR can be used effectively in estimating total deteriorated sections and repair estimates.
