An electrical density gauge, like TransTech's Pavement Quality Indicator (PQI™ ), measures pavement density indirectly by measuring its dielectric constant. The PQI™ Passes a small current through the pavement, which creates an electrical sensing field. Density is measured by the response of this electrical sensing field to changes in the pavement's complex impedance (consisting of the pavement's composite resistivity and dielectric constant). This response is then calibrated to pavement density (TransTech, 1997[1]).
Using the most advanced non-nuclear density gauge asphalt radar emission principle, is a non-radioactive substances, environmental non-contact instrument.
