GSSI introduces for the first time the PaveScan RDM 2.0 asphalt density meter

GSSI is calling the new PaveScan RDM 2.0 the first non-nuclear asphalt density meter. By pushing the PaveScan trolley behind the asphalt roller, the operator can collect pressure and density data in real time for a paving project. The on-board computer displays density, pressure, a line graph, and a contour map of the measurements, and this information can then be used to determine the quality of the pavement, as well as detect any errors, such as poor uniformity and large differences in density, says GSSI. “PaveScan RDM helps avoid such early failures such as bulldozing, cracking, and degradation along the joints.” The company has given PaveScan new sensor design to withstand the harsh asphalt paving environment. The system automatically measures the dielectric value to identify any anomalies in real time. “Unlike other options, such as nuclear density meters or radioactive alternatives, PaveScan does not create any site hazards or require work areas to be closed,” the company says. It can publish either survey methods with dielectric value or void ratio. This technology has been a specification accepted by the American Association of Public Road Transport Officials and Highway Transportation Officials since April 2019, according to GSSI.The company has tested the device with the Maine Department of Transportation, in which the PaveScan is offered as a four-wheel collapsible cart with one choice. Or three sensors. Single sensor buggies can be upgraded to three sensors with a combination. The cart has foldable saw arms with high visibility and heats up in less than a minute when the ambient temperature exceeds 70 degrees, the company says, and another advantage over conventional nuclear and non-nuclear meters is that the system can make hundreds of measurements per minute. The three sensor system can cover up to 6 feet across a lane. PaveScan integrates with the optional Global Positioning System (GPS), and the data can then be used with Google Earth to create a complete project density profile. Contractors can also measure joint stress during their projects, according to InstroTek, which has been named the US and global distributor for PaveScan. “PaveScan has the power to change the way asphalt density measurement,” says Paul Vice President of Sales and Marketing at GSSI Fowler, adding that InstroTek will use its relationships in the paving industry to represent PaveScan for pavement contractors, paving management, material testing laboratories and municipalities, while GSSI will continue to work with agencies. Federal and state. PaveScan weighs 81 to 94 pounds and has 256 GB of storage. The four-wheeled stroller also comes with a Panasonic Toughpad G1, two lithium-ion batteries and a dual-bay battery charger.
