• 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.
