Concrete Cutting Refinement for Crater Repair

Abstract

Research was conducted at the U.S. Army Engineer Research and Development Center in Vicksburg, MS, to evaluate saw-cutting equipment for use by crater repair teams in airfield damage repair (ADR) scenarios. The evaluation included measuring the saw-cutting rates and conical cutting bit wear of commercial saw cutting equipment in both soft and hard PCC mixtures. The investigated equipment included the Vermeer RW1236W and CC1531, Caterpillar SW45 and SW60, and Ditch Witch H1140 wheel saws outfitted with various cutting bits. This report presents the technical evaluation of the various saw technologies and tools for improving the efficiency of sawing around damaged pavement associated with crater repair. Results indicate that the Vermeer saws with the Kennametal SM04 teeth provide the most efficient saw-cutting rates with the least teeth wear, followed by the Caterpillar wheel saws with the Kennametal RP15 teeth. These two saw technologies are recommended to be considered for use by ADR crater repair teams.
