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
