Abstract
A slipform paver comprises a machine frame carried by rolling assemblies, at least two of which being drivable and at least one being steerable, as well as comprising a support arranged on the machine frame for a slipform mould and a controller for controlling the rolling assemblies to adjust the velocities of the drivable rolling assemblies and the steering angles of the one or more steerable rolling assemblies. The controller is configured such that, when the steering angles of the one or more steerable rolling assemblies change, the velocities of the drivable rolling assemblies are adjusted so as to reduce the change in the velocity at which a reference point referring to the support for the slipform mould will move along a predefined trajectory, said change in velocity being caused by changing the steering angle. The quality of the concrete profile produced by the slipform paver is thereby improved.
