GSSI, manufacturer of ground penetrating radar (GPR) equipment, features its industry-leading PaveScan RDM asphalt density assessment tool. The PaveScan RDM provides accurate real-time measurements to ensure pavement life and quality.

GSSI’s PaveScan RDM system has been a valued 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 raveling, 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 per cent 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. The entire system is composed of a cart, one to three sensors, a customized Panasonic G1 ToughBook, a concentrator box and a variety of system accessories.
