      Unpredictable

      climatic conditions paired with the varying topography in Vermont have often resulted

      in dangerous roadway conditions

      .

      Statistics show that many fatalities occur in rural environments like

      Vermont. Federal Highway Administration (FHWA)

      has

      developed many

      strategies to address this issue.

      One experimental treatment that has been used is a high friction overlay known as Tyregrip. Key personnel

      at VTrans chose to evaluate the treatment at a high crash location along VT Route 9 in the town of

      Woodford, Verm

      ont in 2009.

      The treatment was placed on the westbound lane and shoulder at approximately MM 3.0, on

      October 8, 2009. Shortly after the installation Research personnel observed failures in the

      treatment, which

      required attention. In November

      2009,

      the damaged sections were repaired by Ennis Paint, Inc and Total

      Highway Maintenance (THM). In July

      2010,

      significant cracking and delamination failures were observed. It

      was determined a repair was needed however due to limited promoting weather condit

      ions and inflexible

      schedules the repair was planned for the 2011 construction season. After an on

      -

      site meeting with VTrans

      Pavement Management, Materials and Research, and District 1 personnel it was determined

      that,

      the ideal

      repair would be to mill up

      and repave the section with asphalt pavement.

      Based on the limited evaluation period it is recommended that the treatment be installed at a

      different location in Vermont

      .

      The new trial location would preferably be on new pavement, where underlying

      crack

      ing and/or distresses are not of concern to the performance of the treatment
