Non-Nuclear Pavement Quality Indicator
Non-Nuclear Pavement Quality Indicator
Taisei Trading Private Limited / Sinfonia Technology offers Non-Nuclear Pavement Quality Indicator.
TransTech’s Pavement Quality Indicator Model 380 (PQI380) utilizes state of the art technology to get accurate asphalt pavement density readings.
Measurement Technology:
The PQI380 uses Impedance Spectroscopy to measure the electrical response of asphalt from which the density is calculated. As shown in the Comsol simulation below, the electrical field transmits through the material from the sensor plate of the PQI. The impedance is then measured and used in the calculation of the density for that specific aggregate.
