Abstract
The present invention relates generally to paving equipment. More particularly, the present invention relates to a paving material density indicator which has a selectively shaped sensor to control at least one of the depth, area, sensitivity and shape of a density determination. The effect on sensor capacitance is measured using a constant current source and is used to determine density of the paving material. The invention is also a method for determining density of paving material and a set of sensors for density determination.
