Abstract :
The experimental values for the attenuation and phase constant of a two-wire transmission line lying on a concrete roadway are used in conjunction with a model for the transmission line-roadway interface to deduce values of the effective dielectric constant and loss tangent for the roadway material. These are obtained for both dry and wet roadways over a range of frequencies.
