Abstract:The Vermont Agency of Transportation (VTrans) wanted to explore stone matrix asphalt (SMA) as a pavement treatment to improve durability of highways in cold climates, including to withstand rutting from studded tires and high volumes of heavy trucks. A segment of a Sharon-Bethel I-89 project in 2021 provided an opportunity for first placement. Discussions with the Federal Highway Administration (FHWA) in March 2021 to help develop specifications for the placement led to a plan for the FHWA Mobile Asphalt Technology Center (MATC) and technical support team to come to Vermont that June. The visit’s primary goal was to assist VTrans in evaluating the state’s first SMA mixture and comparing it with the state’s standard dense-graded surface mixture.
