	GPR – Ground Penetration Radar – a method for investigation of pavement structures by means of radar. A combination with advanced software, specific knowledge and experience in data interpretation allows definition of pavement layer thicknesses in a road structure. Advantages using GPR measurements An accurate overview of the pavement layer thicknesses is obtained. The method is non-destructive meaning that core taking is not necessary and damages to the pavement are avoided. Detailed information about the pavement structure is obtained compared to the ordinary core taking method. At the same time a very detailed picture of the pavement structure is obtained, which secures an optimum pavement design with less risk of over- or under-designing and a better utilization of funds. The equipment measures at driving speeds of up to 110 km/h and the measurements are made with very little inconvenience to and uptimum security for the traffic. Grontmij | Carl Bro has the equipment to perform GPR measurements including registration of deep layers. Furthermore, we offer supplementary analysis and specific consultancy about bearing capacity, maintenance strategy and selection of pavement type.
