GSSI shows PaveScan RDM asphalt density tool

Published 7/3 at 16:39

GSSI, the manufacturer of ground penetrating radar (GPR) equipment, has announced that its PaveScan RDM asphalt density assessment tool was featured at the Transportation Research Board (TRB) 98th annual meeting.

This was held from 13-17 January 2019 at the Walter E. Washington Convention Center in Washington, with demonstrations being held of the PaveScan RDM at the company’s booth in order to show its accurate real time measurements of pavement life and quality. 

GSSI’s PaveScan RDM system, initially unveiled at the 2016 TRB meeting, is now a valuable addition to the toolbox of solutions for uncovering problems that occur during the paving process, including poor uniformity and significant variations in density. By avoiding these problems, PaveScan RDM helps avoid such premature failures as road ravelling, cracking, and deterioration along joints. 

PaveScan RDM automatically measures the dielectric value to identify anomalies in real time. In addition, the dielectric values can be used to correlate percent voids and density in new pavement. The innovative technology enables users to obtain critical density data for quality assurance/quality control of new pavements. Unlike other options, like nuclear density gauges or radioactive alternatives, PaveScan RDM does not result in any site hazards or require closing off work areas.

Seamlessly integrating with GPS systems, PaveScan RDM features a flexible, modular design that facilitates easy and efficient operation and data collection. It is available as a small, portable single sensor cart based system, or a three sensor configuration using an extended cart or vehicle configuration. The entire system is composed of a cart or vehicle mount, one to three sensors, a customised Panasonic G1 ToughBook, a concentrator box and a variety of system accessories.
