• Abstract:
  Few guidelines exist statewide, or even nationwide, for assisting designers in selecting
  
  appropriate roadway widening techniques. Current Florida Department of Transportation
  
  (FDOT) specifications provide a basic framework for widening hot-mix asphalt (HMA)
  
  pavements. However, the existing guidance does not address alternative construction techniques
  
  and treatments used in current practice for constructing more durable longitudinal joints.
  
  This report identifies factors impacting the performance of flexible road widening with a focus
  
  on the longitudinal joint between existing pavements and new widening sections. A review of
  
  available literature related to lane widening of HMA roadway pavements was conducted, and an
  
  eight-page questionnaire was developed and distributed to State highway agencies (SHAs),
  
  research centers, and industry to determine the state-of-the-practice regarding the design and
  
  construction of longitudinal joints in widened roadway sections.
