Roadtronix Uses LiDAR to Improve Asphalt Paving Smoothness

Roadtronix B.V., Tilburg, Netherlands, announced in August 2026 the launch of Roadtronix, a high-density LiDAR surface measurement system engineered to help asphalt paving crews achieve smoother, more consistent roads while reducing the manual handling and setup complexity associated with traditional averaging systems.

Roadtronix mounts directly to an asphalt paver and uses LiDAR technology to capture thousands of surface measurements per second across the road surface. That continuous stream of data is designed to give crews a more complete picture of the true pavement profile than conventional systems can provide, and it forms the basis for real-time adjustments to asphalt thickness during paving.

For decades, paving crews have relied on mechanical averaging beams fitted with a handful of ultrasonic or sonic sensors to estimate surface elevation. These systems work by sampling a limited number of fixed points along a beam and averaging the results—an approach that has served the industry well but leaves gaps between measurement points and requires bulky hardware mounted to the paver.

Roadtronix takes a different approach. Rather than sampling a few discrete points, its LiDAR sensor captures a dense field of measurements across the entire scan area, many times per second. Because the calculation draws on far more data, the system is less susceptible to isolated highs and lows and produces a more accurate, stable representation of the actual surface, according to the manufacturer. The result, according to the company, is improved International Roughness Index (IRI) smoothness, fewer bumps and more predictable control throughout a paving run.

The system also addresses a persistent challenge with mechanical beams: interference of the beam structure affecting activity and safety around the paver. Workers, vehicles and equipment moving near the machine can be restricted by the physical structure of a traditional beam. In addition, the fixed length of a traditional averaging beam confines its use to long open paving runs without tight corners.

Scan length on the Roadtronix system is adjustable in real time, from short ranges suited to curves, intersections and urban roads and over up to 60 feet for highways, airport runways and other long, open runs. The LiDAR unit does not need to sit directly above the surface it is measuring, giving operators the flexibility to position the scan at a lateral offset to suit site conditions, including narrow roads.

The compact, paver-mounted unit requires no welding or permanent modification and can be installed by a single operator in under five minutes, according to the manufacturer. With a smaller footprint around the paver and less hardware to manage in active work zones, the system is designed to reduce the on-site risks that come with bulkier equipment, without adding complexity for the crew. The unit is supplied in a compact carrying case for transport and storage between job sites.

The system operates independent of ambient light, allowing it to function as effectively for night paving as it does in daylight, and it has been engineered to hold up under the heat, dust and variable conditions typical of active paving sites.

Roadtronix is compatible with a wide range of modern asphalt pavers and is suited to urban roads, highways, airports, race tracks and other asphalt paving applications. In the United States, the system will be supported by Co-founder Mike Milne, who brings an established U.S. paving industry network to support the system’s rollout across the country in early 2027.
