"Plug and Pave" non-contact controls for Asphalt Pavers and Milling Machines

The modular Trimble ScreedPro® System is the ideal choice for improved productivity and accuracy when laying road and runway asphalt. ScreedPro is a non-contact control system for laying asphalt that plugs directly into the automatic control system on Asphalt Pavers and Milling Machines. The configurable paving system can be set up with one or more of Trimble's positioning sensors—Tracer Plus, the Slope Module and a Laser Receiver—to meet your needs.

Using ScreedPro with the Tracer Plus ultra Sonic grade controller, the distance to a reference surface is measured using high frequency sound waves. Simply set up the Tracer Plus over a reference surface; curb lip, previous pass or string lines, to control the precise mat thickness. And if the distance changes, the Tracer Plus sends a correction signal to the machine's control valve.

ScreedPro with Tracer Plus is very easy to install and setup, the non-contact Tracer Plus sensor is a direct replacement of a mechanical grade sensor that simply plugs into the paver as a low cost, expandable replacement for mechanical wands and grade matching ski. When used with the Universal Remote Control, screed operators can use the Tracer Plus control the mat thickness to increments as fine as 1mm, or 0.01 foot, from anywhere on the screed, keeping personnel out of traffic and danger. Combining the Tracer Plus with the Slope Module, provides automatic slope control as well as mat thickness.

For resurfacing airport runways or applications with long continuous grades, the addition of the R2S-2 Laser Receiver, EM2 electric mast and the 1145 dual slope laser transmitter provides the greatest accuracy for day or night time operations.

From subdivisions to runways, ScreedPro is an extremely flexible paving control system, offering the option to use the right sensor for the application—the Tracer Plus sonic grade controller, the Slope Module or the Laser Receiver. Asphalt Pavers and Milling Machines can be set up with one or more sensor for precise control of the mat thickness, improved productivity and reduced material overages.

• reference bale compensates for rapid temperature changes to ensure consistent material depth.
• hand held universal remote interface provides the flexibility to move the control where you need them while making material thickness changes or just setup.
• indicate Mode shows the deviation to grade while in automatic for fine tuning the system
• local and fast equipment service and support
• easily transferable from machine to machine
