Abstract: The invention relates to a road roller primarily for compacting road surfacing materials such as asphalt. The road roller provides an ergonomic workplace for the operator in the cabin of the road roller and offers an unobstructed view of the rollers (4 and 12) and especially of the lateral edges (4a and 12a), respectively, thereof. This is of major importance when positioning the road roller on the surface to be compacted. This is achieved with an asymmetrical arrangement of the cabin; that is, one side of the cabin extends beyond the lateral edges (4a and 12a), and the operator's seat 6, with the steering wheel 7 and controls 8, is pivotally and laterally displaceable within the cabin.

Abstract: A method for operating a hydraulically driven road roller, primarily for compacting bitumen, with which repeated passes are made over a bitumen coating and in which the roller's speed, acceleration, deceleration and direction of travel (forward or reverse) are selected with an operating lever 1 which, via a control panel 8, electrically acts on hydraulic valves (10, 11, 13) controlling a servo 14 which acts on a hydraulic pump 15 driving the propulsion motors of the road roller. The operating lever is moveable from a neutral position to full lever deflection and equipped with a forward/reverse switch 2 for selecting the roller driving direction. The speed of the road roller decreases at a programmed deceleration, when this switch is actuated, until the roller stops, followed by acceleration at a programmed rate to a programmed driving speed in the opposite direction. The roller is brought to standstill at the maximum permissible deceleration when the lever is pulled back.
