Paving Control for Asphalt Pavers

- Lay the finished surface with accuracy to 0.01 feet (3 millimeters)
- Minimize use of expensive material
- Pave within a tighter tolerance and get closer to the minimal asphalt thickness specification
- Reduce labor costs by controlling the screed with one operator
- Eliminate 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
PCS900 3D

- 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
The Trimble PCS900 system leverages the Trimble SPS930 Universal Total Station, MT900 Machine Target and on-board software to compare the actual screed position and slope with the 3D digital design. It automatically guides the screed to lay exactly the right material thickness and slope.

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.
The ST200 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.
The PCS400 system can also use the Trimble AS200 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 0.5% accurately and consistently.
