The PaveScan RDM asphalt-density assessment tool from Geophysical Survey Systems, Inc., (GSSI), a manufacturer of ground-penetrating radar equipment, is designed to provide real-time, nondestructive measurements to determine asphalt integrity during application. The PaveScan RDM system, says the manufacturer, "is ideal for uncovering problems that occur during the paving process, including poor uniformity and significant variations in density." On the technical side, PaveScan automatically measures the dielectric value to identify anomalies, says GSSI, and these values can be used as a means to correlate percent voids and density in new pavement. Seamlessly integrating with GPS systems, says GSSI, PaveScan features a modular design available as a portable, single-sensor, cart-based system or as a three-sensor configuration using an extended cart or vehicle.
