• Abstract:
  A bonded wearing course (BWC) is a gap graded, ultra thin hot-mix asphalt (HMA) mixture applied
  
  over a thick polymer modified asphalt emulsion membrane. The emulsion membrane seals the
  
  existing surface and produces high binder content at the interface of the existing roadway surface and
  
  the gap-graded mix all in one pass. The gap-graded HMA provides an open surface texture to allow
  
  water to flow through the surface. A BWC can be applied and opened to traffic quickly, usually
  
  within 15 minutes, without sanding or tracking. Bonded wearing courses are primarily used in high
  
  traffic areas as a surface treatment over HMA and PCC surfaces. It can be placed over structurally
  
  sound pavements as a maintenance treatment, and may also be used in new construction and
  
  rehabilitation projects as the final wearing course.
