Abstract

Ground Penetrating Radar (GPR) is a geophysical imaging technique used for subsurface exploration and monitoring. The ground penetrating radar (GPR) method involves the transmission of electromagnetic waves into the material under investigation. The reflections of these waves at interfaces and objects within the material are analyzed to determine the location (horizontal distance from a reference point) and depth (vertical distance from the surface) of the detected interfaces and buried objects. These reflections of GPR waves are detected by the receiving antenna and converted into electrical signals. The recorded reflections can be analysed in terms of shape, travel time and signal amplitude to provide information about the size, depth and properties in relation to the material object. Spun pile is a round and hollow pile in the middle. Method making of spun pile is centrifugal for concrete compaction process, that is with how to spin (spinning), there is no possibility will produce an unequal compressive strength on the thickness of the pole wall. The sight of the slurry layer will be possible affecting friction with filler concrete. This study to discuss the friction between the inner concrete of spun pile so new concrete as filler.Determining the thickness of concrete pavement is an important consideration for construction quality assurance of structural capacity estimation of existing. This information is essential for pavement management systems in order to maintain the safety, serviceability, and durability of pavement networks. the depth of spun pile in the area 1, which consisted of two locations, showed that piles rested on 16 m and 20 m below ground. The area 2 which consisted of four spun piles showed the depth of those piles were 13 m, 13 m, 20 m and 17 m for GPR 1,2, 3 and 4 respectively. These results were to confirm as built drawing that showed that the depth of all piles rested on 20 m below ground.
