Planning emerging radio systems, as vehicle‐to‐vehicle or vehicle to infrastructure links, needs deep knowledge on the electromagnetic behaviour of the different materials involved. This Letter describes a system for measuring in‐situ reflection coefficients. Besides, it gives data related to asphalt and concrete, in both wet and dry conditions, in a band from 5.8 to 6.0 GHz. Normal incidence reflection coefficients resulted to be similar in magnitude for both materials in dry conditions, and they experiment an increase of 65% after soaking the pavement. This indicates the strong influence of moisture on the electromagnetic behaviour of common road surfaces.
