    Abstract: The subject matter described herein includes methods, systems, and computer program products for measuring the density of a material. According to one aspect, a material property gauge includes a nuclear density gauge for measuring the density of a material. A radiation source adapted to emit radiation into a material and a radiation detector operable to produce a signal representing the detected radiation. A first material property calculation function may calculate a value associated with the density of the material based upon the signal produced by the radiation detector. The material property gauge includes an electromagnetic moisture property gauge that determines a moisture property of the material. An electromagnetic field generator may generate an electromagnetic field where the electromagnetic field sweeps through one or more frequencies and penetrates into the material. An electromagnetic sensor may determine a frequency response of the material to the electromagnetic field across the several frequencies.

    Abstract: A method of obtaining a material property of a pavement material from a microwave field generally includes generating a microwave frequency electromagnetic field of a first mode about the pavement material. The frequency response of the pavement material in the electromagnetic field can be measured, such as by a network analyzer. The measurement of the frequency response permits correlating the frequency response to a material property of the pavement material sample, such as the density. A method of correcting for the roughness of a pavement material divides the pavement into a shallow layer and a deep layer. Two planar microwave circuits measure the permittivity of the shallow and deep layer. The permittivities are correlated to correct for roughness. An apparatus for obtaining the density of a pavement sample includes a microwave circuit and a network analyzer. The network analyzer measures the frequency response to determine the density of the pavement material.
