Abstract
A device for measuring density and moisture of a material includes a hollow roller rotatably mounted on a shaft for rolling movement on the surface of the material. A radioactive source and density and moisture detectors are supported below the shaft and adjacent to the inner surface of the roller at substantially a fixed distance from the surface of the material being measured as the roller is rolled. The detectors are coupled to a conventional counter and microprocessor circuitry which provide an output reading related to the density or moisture content of the material. The shaft may be mounted for tilting movement so that the roller may pitch in conformity to contours in the material surface.
