• 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
