The condition and quality of the road network play a decisive role in the efficiency of road transport.
The continuous increase in road traffic places an ever-greater burden on road network maintenance, renovation, and repair. Timely execution of maintenance works impacts energy consumption, environmental protection, road user safety, and transportation costs. Pre-planned scheduling of these tasks is essential for sustainable and safe road transport.
Ground penetrating radar surveys can determine layer thicknesses, reveal structural defects, and detect cavities and subsidences on the surveyed road section. Zones where water infiltration occurs can be identified. By repeating measurements on individual sections, temporal changes in pavement condition can be detected. By surveying the condition of roads and highways, we help transport authorities and infrastructure developers make informed decisions regarding maintenance, repair, and pavement renovation. In addition to the handheld measurement cart method optimized for smaller surface measurements, it is also possible to perform large-area 3-dimensional measurements. In this case, the multi-channel measurement system is towed by a vehicle, maximizing data acquisition efficiency.
After evaluating the data collected in the field, we present the identified defects and layer boundaries on the radar sections to the client, prepare coordinate-correct depth sections from the surveyed results, and, if required, spatially represent the distribution of layer thicknesses and the depths of the identified defects on a map.
