GSSI releases asphalt density assessment tool

Published 9/3, 2021 at 15:35

PaveScan 2.0 incorporates a new sensor design built specifically for the extremes of the asphalt paving environment.

It features foldable deployment arms and has a warm up time of under one minute when ambient temperature is over approximately 21°. PaveScan RDM is suited 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 as a means to correlate percentage voids and density in a new pavement. The innovative technology enables users to obtain critical density data for the QA/QC of new pavements. GSSI states that PaveScan does not result in any site hazards or require closing off work areas. Integrating with GPS systems, PaveScan features a modular design that facilitates efficient operation and data collection. It is offered as a single sensor or a three sensor cart based configuration. This pavement density measurement technology is an accepted American Association of State and Highway Transportation Officials specification, PP 98-19.
