• Abstract:
  The researchers performed a synthesis study to evaluate the factors and criteria included in Form 2088. The current state of the practice and emerging research for the criteria used to determine pavement friction demand and availability were evaluated for flexible pavement surfaces. The researchers prepared and distributed a survey to TxDOT and other state departments of transportation to assess the state of the practice involving the criteria used to: Determine friction demand for aggregates used on the surface of flexible pavements. • Determine the friction available on a proposed pavement surface. • Select aggregate properties to meet the friction criteria for flexible pavements.
