ABSTRACT:
Self-propelled pavement patching apparatus is provided and includes a backhoe whose bucket has teeth and a cutting blade at opposite ends thereof and screeding edges underneath, another patch material distributing and screeding device mounted on the apparatus for movement therewith, a hopper for dispensing patch material to a conveyor for selective delivery of patch material to the backhoe or the screeding device. The apparatus is tricycle-type having two wheels at the outside and a third wheel for driving and steering. A roller adjacent one side wheel provides for compacting patching material over pavement defects, and the roller is lowered to raise that wheel from the pavement to form an outrigger corresponding to a conventional outrigger foot adjacent the other outside wheel. A movable outer hopper wall can be lowered for reception of patch material from a dump truck and raised toward a more nearly upright position to facilitate delivery of patching material to the conveyor and for towing vehicle clearance. The hopper is expansible widthwise of the apparatus, and an extensible guide provides a pendent arm contacting the pavement for viewing by the apparatus operator over the hopper for accurately locating the apparatus relative to pavement features. A towing link pivotably mounted adjacent the drive wheel has a towing eye for engagement with a hitching hook on a truck and is pivotable downwardly after engagement for lifting the drive wheel from the pavement for towing the apparatus behind the truck.
