DEVELOPMENT OF A HIGH PRESSURE WATER JET FOR THE RAPID REMOVAL OF CONCRETE

The objective of this program was to design, build and demonstrate a prototype concrete removal unit that utilized water cavitation erosion technology to accomplish the work. This final report presents an in-depth discussion of the significant elements of the program; specifically, the design considerations, the fabrication and laboratory testing and finally the field demonstration. In addition, there are separate sections which include a cost analysis and system comparison and the conclusion and recommendations that resulted from this program. This program has promoted the advancement of water cavitation technology and has demonstrated its cost effectiveness and feasibility to be employed in large scale systems for concrete removal. (FHWA)
