• Abstract:
  Bridges and adjacent highways experience different environmental conditions. Depending on bridge ; height, wind direction and other parameters, pavements are subject to moisture and quick changes in ; temperature. Without the benefit of residual ground temperatures to temper against the cold deck, ; surfaces may freeze first resulting in bridge deck de-icing needs that are different from nearby roadway ; surfaces. An icing event could expose drivers to hazardous conditions for an estimated 90 ; minutes before crews can respond to restore a safe condition. ; This research project was developed and funded jointly by the NHDOT and the Vermont Agency of ; Transportation (VTrans) to evaluate the effectiveness of an automatic anti-icing system, also known ; as fixed automated spray technology (FAST). FAST systems anticipate the formation of ice and automatically ; deploy liquid de-icers to prevent the formation of ice. They also prevent the bond of snow to ; the deck, thereby improving snow clearing efficiency.
