Field Evaluation of the Water Wedge for Cutting Portland Cement Concrete Pavements for Repair and Restoration of Paved Surfaces (REREPS).

Abstract

The Water Wedge 1200 device is 29 in. long, weighs 22 lb, and is manufactured from high strength steel. The explosive cartridge used to drive the Water Wedge is the Hudco WW120 industrial cartridge. This cartridge is actually a blank 12-gauge shotgun shell. To use the Water Wedge device, a 1-5/8-in.-diam. hole is drilled in the pavement, and the hole is filled with water. 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 thue repair and restoration of paved surfaces (REREPS) project.
