• Abstract:
  The vast topography paired with the unpredictability of climatic conditions statewide, result in many high traffic
  
  incident locat
  
  ions on Vermont highways. Such locations may also be difficult to maintain during winter conditions,
  
  which only compounds the unsafe travelling conditions for motorists.
  
  One specific site located along Vermont Route 9 in Searsburg, Vermont has recently
  
  begun exhibiting increased
  
  safety and maintenance problems in the westbound lanes during inclement weather. The Vermont Agency of
  
  Transportation (VTrans) chose to apply an anti
  
  -
  
  icing overlay produced by Cargill, known as Cargill SafeLane® HDX
  
  Overlay. T
  
  he treatment was installed by District 1 maintenance forces in the summer of 2007. Research personnel
  
  were onsite to document the two
  
  -
  
  day installation. During the second day installation, it was noted that water
  
  seepage on the steep grade was evident in
  
  the travel lane. This later arose as a delamination problem over the
  
  length of the overlay system.
  
  Though delamination issues were noted at preexisting cracks, over the course of the evaluation, the treatment
  
  provided traction for vehicles especially m
  
  ulti
  
  -
  
  axle trucks. Considering this factor alone, the treatment was deemed
  
  successful. Due to this success, it was placed in two other locations in the northwest region of Vermont. The first
  
  application was on a bridge deck where frequent and sudden brak
  
  ing had caused many rear end collisions. The
  
  second application was on a downhill lane of a city road, noted to be a high crash location as vehicles were having a
  
  difficult time stopping at the traffic signal at the bottom of the hill. Both provided sign
  
  ificantly different situations, with
  
  a similarly resulting maintenance and safety problems as experienced in the Searsburg location
