• 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.
