A method for transferring crushed rock from a dump truck to the hopper of a paving machine without danger of spillage by interlocking the rear end of the dump bed with the upper portion of the hopper when the dump bed is raised into position to dump into the hopper. The hopper is provided with an upwardly extending centrally located bumper which is adapted to engage and push the rear end of the truck frame during the time the dump bed is raised to transfer aggregate from the dump bed into the hopper while permitting the truck to pivot relative to the hopper.
