Abstract
A precision slot cutting machine for concrete and asphalt pavement includes a self propelled unit with an operator's station and a blade platform is attached to the self propelled unit by a pair of pivot arms which allow the blade platform to freely pivot about an axis parallel to the path of travel of the self propelled unit. The blade platform is supported by a short based wheeled carriage with two independent wheel supporting bars, each of which is attached to the blade platform via a single pivot axis. The pivotal attachment between self propelled unit and blade platform and the independent pivoting action of the wheel supporting bars insure that variations which occur in the pavement surface both in directions parallel to and across the travel path of the machine are compensated for to allow precise cutting of slots of even depth into the pavement.
