Pavement material microwave moisture-density measurement methods and apparatuses
A portable microwave material gauge for determining the quality of a pavement material is provided. The gauge includes an electromagnetic field generator configured to generate an electric field mode that penetrates into the material wherein the material includes a heterogeneous material including at least one of a pavement material and a soil material, a calibration data set, a sensor of size and shape to support the electric field mode and to determine the response of the pavement material to the electric field wherein determining the response includes determining a change in the permittivity as a function of a change in the quality of the material; and an analyzer configured to correlate the sensor permittivity response to the calibration data set wherein correlating the response includes using stored relationships between the material quality and the sensor response using calibration samples having changes in permittivity as a function of quality.
