Paving Control for Asphalt Pavers
Pave the way to better profits. Trimble Paving Control Systems help speed up your paving production while laying a smoother surface and reducing material costs.
Features
Guided by a 2D reference or 3D design model, Trimble Paving Control Systems can help you:
Grader performance
- 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
Configuration
1. PCS900 3D
The Trimble PCS900 3D Paving Control System allows 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
2. PCS400 2D
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.
Surface Reference
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.
Stringline Reference
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.
Slope Sensor Reference
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.
