Trimble Roadworks: Real-time Asphalt Compaction Quality

Pairing Trimble Roadworks with GSSI delivers pass-by-pass compaction data that helps crews monitor asphalt density as work happens and standardize results across a paving train. Trimble Roadworks is a machine-control platform used on road construction equipment to guide operators during paving and milling, keeping work aligned to the design and providing in-cab feedback that supports consistent production.

Trimble Roadworks Platform Adds Pass-By-Pass Metrics

Trimble said its Trimble Roadworks paving control platform for asphalt compactors now works with GSSI’s PaveScan RS, delivering per-pass compaction metrics. In a typical setup, the PaveScan RS radar and DPS sensors capture dielectric measurements as the roller moves, and Trimble Roadworks presents those readings in the cab as the operator completes each pass. This tight, pass-by-pass loop helps crews spot low-density areas early, adjust rolling patterns immediately, and document compaction progress without waiting for end-of-shift checks. In tandem, Trimble and the SITECH dealer network will serve as a global aftermarket reseller of DPS sensors for density profiling, broadening availability across the sector.

Marrying high-speed ground-penetrating radar with Trimble Roadworks lets paving crews map the dielectric profile—an indicator of air voids—throughout asphalt compaction instead of relying on cores taken after completion. For contractors running mixed fleets, radar-derived subsurface intelligence can also be used alongside the positioning and machine-control workflows found across the industry, including Topcon environments, helping teams keep density insights consistent from pass to pass.Accelerate schedules.Optimize resources.Deliver safer outcomes.Deliver more profitable outcomes.Deliver more sustainable outcomes.

Trimble Roadworks Paving Control typically combines in-cab hardware and connected sensors with on-screen guidance tools. Common components include an operator display, GNSS antennas and receivers, and machine-mounted sensors; the operator interface provides map-based guidance, configurable targets, and clear visual prompts so crews can follow the design, verify coverage, and respond quickly to out-of-tolerance areas as they work.

On connected projects, Trimble WorksManager can be used to move data between office and field systems supporting road construction. A common workflow is to build and review designs in Trimble Business Center (TBC), publish job files through Trimble WorksManager, and then synchronize them to Trimble Siteworks for site layout and to Trimble Earthworks for machine guidance; field updates and as-built data can be sent back through WorksManager for review and reporting in TBC. Exchanged content commonly includes design surfaces and models, alignments and linework, control points, and job files, along with field-captured data such as as-built points, production records, and status updates in supported CAD and machine-control file formats.

Trimble WorksManager can also support coordinated handoffs between Trimble Roadworks and other Trimble solutions by keeping current design data and job revisions aligned across equipment and teams. This reduces manual file handling, helps standardize what each operator is working to, and supports faster issue resolution when design changes or field conditions require updates.

Related Trimble solutions used alongside Trimble Roadworks in road construction include Trimble Roadworks Milling Control for milling guidance, Trimble Earthworks for grade control on earthmoving equipment that supports roadway preparation, Trimble Siteworks for layout and verification, and Trimble Business Center for design preparation and post-processing.

Machine-control technology in road construction can improve accuracy to design, reduce rework, increase production consistency, and strengthen quality documentation by turning key checks into in-process operator feedback rather than end-of-shift corrections.

GSSI PaveScan RS Enables Live Density Mapping

Allowing compactor operators to watch density as they work streamlines rolling. They can validate target density before moving on, rather than finishing the job and drilling cores to check it. — Kevin Garcia, General Manager, Civil Specialty Solutions, TrimbleWhen compaction results are visible in real time, quality control becomes an on-the-spot decision instead of a delayed discovery.

Project-wide, real-time visibility removes guesswork from roller patterns and cuts the risk of rework or fines for missing compaction specifications. The result is longer-lasting, lower-maintenance asphalt paving and simpler closeout because verification can rely less on coring after compaction is complete.
