Pavement material microwave density measurement methods and apparatuses

摘要

A method for determining a material property of a material is proposed, the method comprising: generating an electromagnetic field including two or more frequencies and penetrating into a material, wherein the material includes at least one of a pavement material and a soil material; determining a frequency response of the material to the electromagnetic field across the two or more frequencies; and correlating the frequency response of the material to a material property of the material.
