Abstract
The invention provides an asphalt patching device capable of single-handed operation, reducing the time and expense of conventional asphalt patching. The device comprises an auger, a hopper with an associated spreader, a conveyor to transport asphalt from the auger to the hopper, and an operator'"'"'s station. This device, exclusive of the hopper, is mounted to a wheeled frame which is pulled behind a dump truck carrying the asphalt. The frame is provided with wheels which permit the device to rotate substantially 180° side-to-side behind the truck in order to effect asphalt patches on a roadway.
