GSSI Releases PaveScan RDM 2.0
GSSI has released the PaveScan® RDM 2.0, which is an asphalt density assessment tool designed to provide real-time measurements to ensure pavement life and quality. The company unveiled PaveScan RDM 2.0 for the United States and Canada at the Transportation Research Board 2020 Conference in January.
PaveScan 2.0 incorporates a new sensor design built specifically for the extremes of the asphalt paving environment, foldable deployment arms with high-visibility for work site safety and has a warm-up time of under one minute when ambient temperature is over 70° F. The manufacturer states it PaveScan RDM is ideal 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.
This system automatically measures the dielectric value to identify anomalies in real-time. In addition, the dielectric values can be used as a means to correlate percent voids and density in new pavement. The technology enables users to obtain critical density data for quality control/quality assurance (QC/QA) of new pavements.
Integrating with GPS systems, PaveScan features a flexible, modular design that facilitates easy and efficient operation and data collection, according to the manufacturer. It is offered as a single sensor or a three-sensor cart-based configuration.
As of April 2019, this pavement density measurement technology is an accepted American Association of State and Highway Transportation Officials (AASHTO) specification, PP 98-19.
