Guided by a 2D reference or 3D design model, 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


WHAT SYSTEM DO YOU NEED?

SITECH Trimble 3D Paving Control System3D PSC400

Trimble PCS900 provides the accuracy and flexibility of 3D technology and allows you to pave with variable depth and slope based on the 3D design.

Accurate 3D control of the screed allows you to:

  • 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

PLUS, with PCS900 Paving Control System 3D technology, you eliminate the time consuming and costly step of setting out string line. Trucks can move easier with less travelling and maneuvering around string lines.

PAVE TO A DESIGN

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.


SITECH Trimble 2D Paving Control System
2D PSC400

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.
