ABSTRACT:
Apparatus and methods for controlling the operation of a pavement surfacing machine are described. One embodiment that controls a pavement surfacing machine having a vehicle moveable in a preselected direction of travel along a pavement surface under the influence of a prime mover and configured to urge a rotatable grinding head against the pavement surface includes at least one sensor configured to measure a preselected operational parameter of the pavement surfacing machine and provide an output representative of the parameter and a controller that is configured to control the rate at which the vehicle moves in response to the sensor output.
