Development of an Advanced Pavement Deicing System
Current methods for winter maintenance of pavement surfaces consist of plowing and application of corrosive deicing agents. These chemicals are hazardous to the environment and hence, their use needs to be minimized. Over 20 years ago, the Connecticut Department of Transportation investigated the use of 300 psi pressurized salt brine jets to enhance the deicing performance. Despite promising results from several field trials, technical difficulties led to abandonment of this technology in the early 80s. Recent advances in high pressure jetting technology suggest that the use of high pressure jets in conjunction with improved chemical agents for pavement deicing may now be practical. In this study, the application of modern high pressure jetting technology as a means of pavement deicing is explored. The proposed system removes ice and snow through the combined action of mechanical jetting forces and controlled use of deicing chemicals. Appropriate operating parameters and consumption rates are identified and compared to the ConnDOT system developed in the 1970s.
