Guidelines for Prioritizing Bridge Deck Anti-Icing System Installations. Phase 1 and Phase II Report
Severe winter weather creates hazardous driving conditions that invariably lead to increased vehicular accidents. One of the major problems is the freezing of moisture on bridge decks, which occurs well before moisture freezes on the rest of the roadway surface. Unsuspecting drivers often lose control of their vehicles while traveling over frozen bridge decks, leading to the unfortunate consequences of traffic accidents. Some states have successfully used bridge deck anti-icing systems, which automatically apply deicing liquid chemicals to bridge decks when icing conditions are detected. Thus, these systems prevent moisture from freezing and bonding to the bridge deck. The Nebraska Department of Roads (NDOR) district offices have proposed several installations of bridge deck anti-icing systems. However, highway funds are not sufficient to install these systems at all of the proposed locations. Therefore, a method of prioritizing bridges for the installation of anti-icing systems is needed to facilitate effective deployment. Although various heated bridge deck technologies exist, the focus of this research was on automatic anti-icing spray systems.
