ABSTRACT:
An attachment for dump trucks having a dump bed with a chute leading downwardly to a discharge end for discharging material along a roadway surface. The attachment adapts the truck to perform roadway surface repairs by receiving, grading, and pressing roadway repair material into place along damaged areas of the roadway surface while the truck is driven forwardly. The attachment includes a blade that is pivoted to the truck at a position rearwardly adjacent the chute discharge end. The blade is arched to receive and grade loose bulk repair material delivered from the dump truck bin through the downwardly projecting chute. The blade is also pivoted between an operative position, riding along the roadway surface, and an inoperative position above the roadway surface. Material delivered to the blade and graded thereby can be compacted and pressed into damaged roadway areas by the supporting truck tires.
