Corporate name Rijkswaterstaat Project Asfaltbekledingen Date 2007-05-01 Abstract In May 2007 Roadscanners did a series of Ground Penetrating Radar (GPR) surveys on two dikes in the Netherlands, one in Friesland and the other in Hellegatsdam. The purpose of these surveys was to determine pavement layer thickness for safety assessment reasons and to produce seed thickness values for FWD back calculation. Another goal was to locate degradation, cracks, voids and other indicators of poor quality structure in the top layers of the dikes. For this task a 3d ground penetrating radar technique was chosen to provide better area coverage over the dike. With a traditional single channel GPR system the limiting factor is that it only gives information along a single narrow line. A 3d GPR collects data from a 2.4 m wide area in a single run, providing a three dimensional view of the dike structures.This report provides a summary of the key research results from the Friesland (Koehool-Westhoek) dike.
