Abstract:
An apparatus for paving a narrow gauge trench in a concrete roadway is adapted to be attached to a vehicle having a supply of pressurized hydraulic fluid and includes a frame having opposing ends and operable to be attached to the vehicle. The frame includes a hopper attached at a first end thereof, an auger disposed therein, and a concrete dispensing aperture extending through a lower wall thereof at a second end of the frame opposite the hopper. A strike-off member is hingedly attached to the frame and a roller is hingedly attached to the frame and extends rearwardly of the strike-off member. A hydraulic system is connected to the pressurized hydraulic fluid supply of the vehicle and is operable to control the auger, the roller, and the vertical orientation of the strike-off member and the roller. When the hydraulic system is pressurized by the fluid supply, a concrete mixture is placed into the hopper and the vehicle is oriented adjacent the trench and moved along the longitudinal axis of the trench, the strike-off member and the roller are lowered to the roadway surface, the auger moves the concrete from the first end to the second end of the frame, the concrete exits the frame from through the dispensing aperture, the strike-off member directs the concrete mixture into the trench and the roller smoothes the concrete mixture in the trench and pushes the concrete mixture farther down the trench as the vehicle moves down the longitudinal axis of the trench.
