• Abstract:
  In Colorado, approximately 60 million scrap tires have been stockpiled and approximately 4.5 million scrap tires are ; generated annually. While CDOT does not generate these scrap tires, CDOT does have goals and policies to promote ; sustainability/recycling and receives requests for more traffic noise barriers than can be funded. CDOT identified an ; opportunity to combine these two topics by investigating new ways to incorporate scrap tires into highway noise ; barriers. ; This research project reviewed potential noise barrier materials made from scrap tires, selected a material for field ; testing, designed and built a test barrier at the designated site using the material, and monitored barrier performance for ; one year. The material selected was a railroad tie replacement made from scrap tire treads. ; Although not originally developed as a noise barrier material, the railroad ties were found to be effective. The ties ; provided a substantial noise reduction, consumed a number of scrap tires, had substantial internal strength that is a plus ; as a building material, and were easily assembled in a post-and-panel barrier design. The barrier performed well over ; its first year. The material and the wall design are recommended for consideration by CDOT on other projects. ; Some challenges were identified through the project: the ties were not a low-cost alternative for reasons stated in the ; body of the report; the finish stain method may need adjusting for a better long-term appearance; rust will appear on ; the steel components; and a few minor construction/finish improvements were identified.
