Trimble Paving Control Systems can help you:
- 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
2D PCS 400
- Trimble PCS400 Paving Control System uses a 2D reference to pave with a fixed thickness. This makes the PCS400 an excellent, lower cost option for roads that have been graded or milled using 3D machine control.
Using PCS400 you can:
- Reference off a surface: 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.
- Reference off stringline: 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.
- Reference off a slope sensor: 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.
