Abstract: A paving material analyzer system is disclosed that uses paving material impedance to determine paving material density. The invention also includes methods for analyzing paving material, in particular, determining paving material density. The paving material density can also be used to determine a percentage of maximum compaction. A paving material analyzer system is also disclosed that determines paving material density regardless of moisture presence on the paving material or a standoff distance of a sensor to the paving material. Sensor circuits providing for improved accuracy are also provided.

Abstract: A sensor for a paving material analyzer is disclosed including means for allowing moving, non-dragging contact of an operative component with the paving material. A paving material analyzer system incorporating the sensor is also disclosed. The invention also includes a method for analyzing paving material.

Abstract: A paving machine and pavement edger therefor are provided. The pavement edger is capable of creating a stepped tapered ramp having a highly compacted step and a highly compacted upper portion of the tapered portion. The resulting ramp allows for safety during pavement laying work stoppage and creation of solid pavement joints.

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.
