GSSI Highlights Innovative PaveScan® RDM 2.0 Asphalt Density Assessment Tool at 2022 Transportation Research Board Meeting

GSSI, the world’s leading manufacturer of ground penetrating radar (GPR) equipment, announces that it will feature its industry-leading PaveScan® RDM 2.0 asphalt density assessment tool at the Transportation Research Board’s (TRB) 101st Annual Meeting, which takes place January 9-13, 2022 at the Walter E. Washington Convention Center in Washington, D.C. Drop by Booth #831 to see a demonstration of PaveScan RDM 2.0, which uses the dielectric measurements of new pavement to determine pavement quality and uniformity.

GSSI’s PaveScan RDM system, initially unveiled at the 2016 TRB meeting, is now an important addition to the jobsite to uncover problems that occur during the paving process, including poor uniformity and significant variations in density. By avoiding these problems, PaveScan RDM 2.0 helps avoid premature failures such as road raveling, cracking, and deterioration along joints.

PaveScan RDM 2.0 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 2.0 does not result in any site hazards or require closing off work areas.

Seamlessly integrating with GPS systems, PaveScan RDM 2.0 features a flexible, modular design that facilitates easy and efficient operation and data collection. This system is available as a small, portable single sensor cart-based system or a three-sensor configuration. The entire system is composed of a cart, one to three sensors, a customized Panasonic G1 Toughpad, a concentrator box and a variety of system accessories.
