Abstract
Dielectric values of cooling asphalt are obtained despite the presence of water on the surface thereof which effects the measured dielectric. The temperature of the surface of the asphalt is measured simultaneous or contemporaneous to a measurement of the dielectric, the former by way of an infrared camera and the latter by way of a ground penetrating radar transceiver, in embodiments of the disclosed technology. The ground penetrating radar moves with a roller on the surface of the asphalt and the camera can also move with and be mounted on the housing or can be separate, such as in a drone flying at a higher altitude than the asphalt and housing. Using a reference measurement for the mix design of the asphalt without water or with varying degrees of water, the changed dielectric due to the presence of water can be corrected to reveal the dielectric of the asphalt alone.
