The device uses a computer integrated into the machine, GPS receivers mounted on the paver and a control panel.

To create the stringline, the receivers communicate with GPS reference station, which measures and stakes out the section to be paved, allowing the Field Rover to plot the optimum course.

The course data is downloaded onto a USB thumbdrive that is inserted into the slipform paver’s machine control, allowing operators to work without entering data manually. The machine adjusts its position and paving heights according to the data.

Wirtgen has said the system is priced lower and less complex than existing 3D systems and requires little training.

Wirtgen won for its “AutoPilot Field Rover” entry, which “accelerates the processes in road construction, saves costs and delivers higher quality.” The system collects measurement data and creates a “virtual stringline” that is downloaded to a USB stick, which is inserted into a slipform paver’s machine control and directs where the paver goes.

The rover can be used with little training, enhances safety and reduces the chance of machine damage.
