Trimble Roadworks

• Lay the finished surface with accuracy to 3 mm
• Minimize the use of expensive material
• Pave within a tighter tolerance and get closer to the minimal asphalt thickness specification
• Reduce labour costs by controlling the screed with one operator
• Reduce operator mistakes with the easy-to-use display interface
• Lay complex designs such as transitions, super-elevated curves and frequently changing cross slopes
• Achieve accuracy and smoothness specifications, which can mean a bigger bonus

The Trimble Roadworks 3D Paving Control Platform and Trimble PCS900 3D Paving Control System allow you to accurately control the screed to pave with variable depth and slope based on a 3D design.

• Take out high and low areas early in the process with the less expensive first layer materials
• Increase road smoothness while using less asphalt than with traditional paving methods
• Lay complex designs such as transitions, super-elevated curves and frequently changing cross slopes
• Achieve accuracy and smoothness specifications, which can mean bonus income
• Eliminate the time consuming and costly step of setting out stringline

• Create a 3D model in Trimble Business Center and load onto the in-cab display
• Use the SPS930 Universal Total Station and on-board software and hardware to compare the actual screed position and slope with the 3D model
• The system automatically guides the screed to lay exactly the right material thickness and slope

Trimble Roadworks 2D Paving Control Platform uses a 2D reference to pave with a fixed thickness. This makes Roadworks an excellent, lower cost option for roads that have been graded or milled using 3D paving control.

Each side of the paver is typically equipped with one sonic tracer or with three sonic tracers mounted on an averaging beam. These sonic tracers send multiple sonic signals to reference off the existing surface and calculate an average elevation for paving a smooth surface.

A sonic tracer can be configured to use stringline as a reference line to control the paver. In this mode the sonic tracer will measure any lateral movement of the machine relative to the stringline. When the sonic tracer’s center is moving away from the stringline, the control box warns you and provides correction guidance.

Trimble Roadworks can also use an angle sensor to reference the desired cross-slope of the road. Designed specifically for asphalt pavers, the sensor rarely needs recalibration and paves cross slopes of up to 0.05% accurately and consistently.

Use a Trimble LR410 Laser Receiver with the GL700 Grade Laser series to reference a laser plane for asphalt thickness control. Both dual and single laser receivers are supported.
