ABSTRACT:
A method and a device for determining the condition of roadway surfaces includes transmitting electromagnetic radiation at at least two different frequencies in the GHz range, reflecting and/or scattering the electromagnetic radiation by the roadway surface and subsequently receiving the electromagnetic radiation at the at least two frequencies. The condition of the roadway surface is determined on the basis of a comparison of the radiation intensities received at the different frequencies.
