PaveScan RDM 2.0: Non-Destructive Asphalt Density Testing

PaveScan RDM 2.0 from Geophysical Survey Systems Inc. (GSSI) is the second-generation asphalt density assessment tool that is perfect for unveiling inconsistencies that take place at the time of the paving process, such as poor uniformity and considerable variations in density. By detecting these issues, PaveScan RDM 2.0 aids to avoid premature failures like road raveling, cracking and deterioration along joints.

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.

Innovative Technology

The PaveScan RDM 2.0 provides a simple and inexpensive assessment tool to non-destructively identify asphalt dielectric at the time of application. This system is perfect for unveiling inconsistencies that take place during the paving process, such as poor uniformity and considerable variations in density.

Groundbreaking Solutions

The PaveScan RDM 2.0 is the premier asphalt test method to determine areas of non-conformity in new pavement. It could be deployed with two distinct survey techniques: using the percent voids or dielectric values. There are no site hazards or need to close off work areas as is the case with nuclear gauges or radioactive alternatives.

Data Visualization

From technician to engineer, the PaveScan RDM 2.0 is simple to use. Thanks to persistent real-time onscreen data output, GPS integration and export options, this system is perfect for government transportation agencies and paving contractors in a similar way.
