A Survey of Anti-icing Practice in Virginia

About the report:

This study documents the current Virginia Department of Transportation's anti-icing practice so that development of a coordinated statewide plan for implementing anti-icing technology can be considered. The researcher surveyed VDOT managers to determine who is using anti-icing technology. Based upon the results of the initial survey, the researcher conducted follow-up interviews. This report uses anecdotal survey information to assess the effectiveness of various anti-icing techniques used within VDOT. The report concludes that where anti-icing practice has been implemented on a widespread basis, the results validate the findings of the Federal Highway Administration (FHWA) Study TE 28 and the anti-icing experiences of other states. The report recommends that anti-icing practices for snow removal and ice control be implemented statewide for roads with a bare pavement policy. Initial implementation should focus on pre-wetting technology and the timely distribution of weather information to the area headquarters level. Pilot testing of direct liquid application technology should continue. Anti-icing practices that reduce chemical usage and the cost of snow removal and ice control while maintaining or improving level of service should also be evaluated. Finally, an anti-icing training program should be developed and taught statewide at the area headquarters level to facilitate implementation, improve current application and to transfer this state-of-the-art technology to the private sector.
