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.
