A road resurfacing device has a frame on which is mounted a ripper bar for ripping the road surface, to a controlled depth, and behind it a separator for separating coarse and fine material in the road surface such the coarse material is deposited on fine material. The frame is supported by rollers extending across the frame. The ripper bar has depending teeth in rows on both sides of the ripper bar and is rotatable so that either sets of teeth, which may be at different heights, rip the road surface. The separator is formed of ground turning discs mounted on angled shafts to direct material first to one side and then to the other. The ground turning discs rotate counter to the direction of movement of the frame. A method of resurfacing a gravel road includes ripping the surface of the gravel road to break up fine and coarse material near the surface of the gravel road; and separating coarse material from fine material such that coarse material is deposited on top of the fine material. The road may then be graded. The depth of rip is controlled to rip up gravel and not penetrate the sub-surface of the gravel road. The ripping and separation functions are achieved by moving the road resurfacing device of the invention across a gravel road behind, in front of or under a grader or tractor.
