Trimble’s new Roadworks 2D Paving Control Platform provides automatic screed control for asphalt pavers.

The company says the system can be mounted to new and existing pavers of any manufacturer.

The system is designed to improve paving accuracy and speed. The Android-system software is easy to use for operators of all skill levels, the company says.

The system automatically paves to a fixed thickness and can be used for such tasks as highways, state roads, airports and large commercial projects. It uses the same interface as Trimble’s Earthworks Grade Control Platform and many of the same sensors as the PCS400 2D Paving Control System.

Along with software, the system comes with the company’s 7-inch TD510 touchscreen and two external keypads. A Trimble LR410 Laser Receiver is used with the GL700 Grade Laser to reference a laser plane for thickness control. The system can handle single and dual laser receivers.

Sensors can be changed quickly, the company says. Operators can use a combination of sonic tracers, slope sensors, averaging beam and contact sensors.

The sonic tracers are mounted to the sides of the paver or on an averaging beam and send out signals to calculate an average elevation to achieve a smooth surface. A sonic tracer can also be configured to use stringline as a reference line.

An angle sensor can be used to reference the desired cross slope with up to 0.05 percent accuracy, Trimble says.
