Available in PDF, EPUB and Kindle. Book excerpt: This research presents the results from laboratory-scale and in field testing to evaluate protective coating systems for corrosion prevention on snow and ice equipment. In total, four organic coating systems and two metalized coating systems were tested on four metal surfaces. A cost-benefit model, based on laboratory data, suggests that exposed metal surfaces on new DOT snow and ice equipment should be coated with either Raptor or LCCOAT to protect against corrosion. DOT snow and ice equipment in need of refurbishment should be stripped down and coated with either Raptor or LCCOAT; trucks in no need of refurbishment should be maintained (visual inspection and coating touch-ups) as is in order to prevent the need for refurbishment. In field results corroborate the cost-benefit model, with further in field testing validation recommended

This book was released on 2016 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current estimates suggest that the United States loses over $220 billion dollars due to corrosion each year. The research results from this project further ODOT's effort to implement a corrosion prevention strategy that will increase public safety by preventing unexpected snow and ice equipment failures, decrease downtime, and provide cost savings through reduction in rust-related maintenance. Protective coatings could increase equipment lifetime and decrease maintenance costs, however, there is limited corrosion resistance performance data available. In this work, laboratory and in field testing were used in combination with cost-benefit analysis to identify cost-effective, field-tested coating systems. Based on these results, a draft standard operating procedure for coating equipment was developed proposing that extra features added to any new assembled dump truck should be painted with either Raptor or LCCOAT as a protective coating. Some of the parts to be coated include the rear hitch plate, hydraulics attachment plate assembly, front plow hoist/ frame/ bumper assembly, liquid deicer tank mounting hardware, and bed hoist subframe. Parts may be galvanized. Trucks in need of refurbishment should be stripped down (sandblasted, prepared and primed to industry standards) and painted to the specifications of the coating system. Trucks in no need of refurbishment should be maintained using visual inspection and coating reapplication where coating breakdown (exposed metal) occurs, in order to avoid the need for total refurbishment. Extra care should be taken to inspect the truck frame (front to back), bed hoist subframe, front plow hoist, front plow frame, front bumpers, rear hitch plate, liquid deicer tank mounting hardware, and hydraulics mounting plate assembly.
