PQI PicSafe, Lightweight, Accurate!

The Pavement Quality Indicator™ (PQI) utilizes state of the art technology to get accurate asphalt pavement density readings quickly, and without the headaches and expenses associated with a nuclear density device. (ASTM D 7113, AASHTO TP68)

The PQI is a Pavement Quality Indicator designed and built to take quick, accurate measurements of hot mix asphalt density.
