GSSI Launches Asphalt Density Assessment Tool
The new PaveScan RDM 2.0 asphalt assessment tool from Geophysical Survey Systems, Inc., provides real-time measurement of pavement life and quality.
Now available in the United States and Canada, the tool 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 company promotes PaveScan RDM as being 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.
Its solution automatically measures the dielectric value to identify anomalies in real-time. In addition, the dielectric values can be used to as a means to correlate percent voids and density in new pavement. The innovative technology enables users to obtain critical density data for QA/QC of new pavements. Unlike other options, like nuclear density gauges or radioactive alternatives, PaveScan does not result in any site hazards or require closing off work areas.
Seamlessly integrating with GPS systems, PaveScan features a flexible, modular design that facilitates easy and efficient operation and data collection. It is offered as a single sensor or a three-sensor cart based configuration.
The tool is approved under American Association of State and Highway Transportation Officials (AASHTO) Specification PP 98-19.
