A road base building apparatus is described that is adapted to be attached to the support ring of a conventional road grader. The apparatus includes a mounting frame for supporting a plurality of rotating scarifiers, a shoveling assembly and a split moldboard strikeoff with the two portions thereof oscillating in opposite directions. The scarifiers are adapted to loosen and/or mix the rock base material to a uniform consistency. The shoveling assembly functions to laterally distribute the material while the pair of strikeoff portions operate to effect a leveling and smoothing of the material. A V-plow is also adapted to be attached to the conventional road grader forward of the rotating scarifiers for laterally distributing the earth or base material deposited ahead of the apparatus. The various components of the apparatus are driven by hydraulic motors operatively connected to a hydraulic pump which, in turn, is connected to the engine of the road grader through a power takeoff located at the rear of the grader.
