Use of Ground Penetrating Radar for detection of salt concentration on Norwegian winter roads
The use of salt for iceandsnow prevention and removal is practised in many countries in order to maintain a high level of mobility and safety during the wintertime. Today winter serviceability comes within a new scope where environmental considerations are very important. Due to lack of calibration of spreading methods, quantity of salt applied is usually not accurately determined. The Ground Penetrating Radar can be a useful tool in salting operations. It records the electric echoes induced by the dielectric properties differences between two materials. GPR can detect salted/non salted surfaces, especially when spread with brine. The amplitude of a single reflected signal is dependent on the brine concentration. This pilot study verifies this effect. However, the equipment and software used for the pilot need modifications to become a practical tool.
