WESTMINSTER, CO, Mar 5, 2026 – Trimble will integrate the PaveScan RS radar sensor from Geophysical Survey Systems Inc. (GSSI) into the Trimble Roadworks paving control platform for asphalt compactors. The update provides asphalt compaction and density data with every pass, improving visibility during paving operations. Trimble and its SITECH dealer network will also resell GSSI’s density profiling sensors (DPS) worldwide, expanding access to DPS across the paving industry.
Ground penetrating radar integrated with Trimble Roadworks allows contractors to measure asphalt dielectric profiles, including air void levels, during compaction. The system records quality control data on every pass* instead of relying on core samples taken after paving is finished. The data helps contractors shorten project timelines and support planning of equipment and crews.
“Giving asphalt compactor operators the ability to monitor compaction quality as they go can significantly improve compaction workflows,” said Kevin Garcia, general manager of civil specialty solutions at Trimble. “Now, an operator can ensure that the asphalt density is correct before they leave the area, rather than waiting until the job is done and then drilling holes in the asphalt to test the density.”
Quality monitoring during paving helps contractors adjust roller patterns and reduce the risk of rework or penalties tied to compaction standards. The approach supports construction of roads designed to last longer and require less maintenance. It also removes the need for coring after project completion, which can improve safety for road crews on site.
“Until now, the only reliable way to determine the compaction quality of asphalt paving is by cutting cores next to live traffic the following day,” said Curt Turgeon, paving engineer at the Minnesota Department of Transportation. “Contractors Quality Control typically requires gauge readings amongst the truck and roller traffic. Reducing or even eliminating these kinds of exposures is essential to creating the safest workplace possible. The immediately accurate full-width quality control feedback to the operator and foreman make this integration compelling, but the safety benefits alone are enough to make this a game-changer for anyone involved with asphalt paving.”
“We are proud to announce this integration with Trimble, a widely recognized leader in paving technology solutions,” said Chris Green, president and chief executive officer at GSSI. “Momentum has been building around DPS with both contractors and road owners over the past few years, and collaborating with a forward-leaning aftermarket supplier like Trimble was the obvious next step in the widespread adoption of PaveScan RS. With this integration, Trimble Roadworks customers can improve safety, lower project costs, and significantly reduce rework on asphalt paving jobs.”
