Abstract: The Water Wedge is a portable hand tool designed to demolish rock, concrete, and reinforced concrete. This study determined the suitability for cutting portland cement concrete (PCC) pavements in bomb damage repair situations. Test holes were made in an existing 12-in. PCC pavement, and a series of tests were conducted with two explosive charge cartridges. Results indicate that the Water Wedge is not an effective means of producing a smooth break in a 12-in.-thick PCC slab especially when used away from one or more free edges. The time required to accomplish the cut was also considered too long for the repair and restoration of paved surfaces (REREPS) project.
