Abstract: Pavement repairs are made by a single person working alone with the new repair apparatus. Blacktop is stored in a sander bin on a truck. An operator periodically replenishes a hopper from the sander bin by aligning the hopper under a discharge assistant of the sander bin and activating the discharge assistant. Standing on a platform at the side of the frame, the operator moves hydraulic controls to move a carriage with hydraulic cylinders from side to side and back and forth on a frame cantilevered from the rear of the truck and anchored to the truck body beneath the sloping sides of the sander bin. The operator aligns an auger guide mounted on the carriage with a hole and lowers a digging auger into the hole. Loose material is removed by air blasts and vacuum. The operator then raises the digging auger and moves the carriage to align the lower end of a sloping discharge chute over the hole.

Abstract: A pavement patcher has a frame supported on the back of a truck. An operator's platform is movable horizontally and transversely on the frame across the back of the truck, and longitudinally for a short distance. The platform carries a hydraulic control console and a blacktop hopper with a hydraulic rotor and an auger. The platform also carries a steel roller mounted on hydraulic rams. The truck driver stops with the frame over a hole. The operator riding on the platform positions the side delivery opening at the bottom of the hopper next to the hole and operates the auger to dispense the required amount of blacktop. The operator then extends the rams to lower the roller and moves the platform to roll the roller across the patch. Significant force is developed on the roller from the hopper's platform, carriage, frame and truck to seal the patch. A hydraulic package is mounted at a side of the frame with a motor, pump and reservoir.
