A STUDY OF HIGH PRESSURE WATER JETS FOR HIGHWAY SURFACE MAINTENANCE

The objective of this program was to develop the performance data that is needed to determine the feasibility of using high pressure water jets as a tool for rapid pavement repairs. Two types of water jets were studied in the laboratory and field investigations: continuous jetting and pulsed jetting. The results of this work were compared to conventional cutting techniques. Plain concrete, reinforced concrete, and asphalt concrete pavements were tested to determine the limitations and applications of the jetting process. Results of the program indicate that the pulsed jet system must be further improved to increase the power output, reduce the size and weight, and simplify the operation and maintneance. Cutting data using the continuous jetting system, using an economic analysis as the means of comparison with conventional systems, shows that continuous water jetting is superior to conventional methods of cutting and removal of concrete. /Author/
