Offset Paving Uses Stringless Control

In offset paving applications, the wet concrete is transferred from the concrete mixer to the slipform mold by means of a feeding conveyor.

The concrete in the slipform mold is compacted and molded as the paver advances. The monolithic profile is produced in the desired form at the outlet of the slipform mold. Various parameters can be set to meet the specific requirements of the application and the profile to be paved.

The Wirtgen AutoPilot system is used for high-precision, stringless control of slipform pavers. The system consists of a base station, a tablet computer, and the control unit integrated in the paver. As the system is designed to eliminate the need for setting up and removing the stringline conventionally used for machine control, it also reduces the associated project times and costs, the company says.

Instead of the stringline, the machine is guided along a virtual stringline by satellite-aided navigation. This is meant to make the entire workflow faster, more efficient and, in turn, more cost-efficient. At the same time, it also makes the paving of complex geometries such as tight radii or S-bends significantly easier.
