• Abstract:
  Asphalt concrete overlay on the existing pavement is often used as a cost-saving
  
  surface treatment for deteriorating pavements. A major problem encountered with asphalt
  
  resurfacing is the phenomenon termed reflective cracking, the propagation of existing
  
  cracks from old or existing pavement into the new overlay. Reflective cracking is one of
  
  the most significant factors in pavement deterioration. It is caused by shear and tensile
  
  stresses in the asphalt layer induced by traffic loads, change in temperature, expansive
  
  subgrade soils, moisture changes, existing cracks, and joint and crack movements in the
  
  underlying pavement.
  
  In this project, the available literature on the applications and effectiveness of
  
  stress-relieving interlayers, known as paving fabrics, to reduce reflective cracking is
  
  synthesized. Basic functions of paving fabrics, fabric specifications, mechanism, long-term
  
  performance, life cycles and cost effectiveness, factors influencing performance, recent
  
  innovations, and lessons learned from installation are discussed. In addition, a survey of
  
  the current paving fabric applications in the State of Mississippi was conducted to
  
  determine the various practices and performances of the paving fabric systems to reduce
  
  reflective cracking. The field performance of overlays using fabric interlayers has
  
  generally been successful, although there have been cases where the paving fabric systems
  
  provided little or no improvements. In particular, paving fabrics may not reduce cracking
  
  significantly with thin overlays. A summary of current practices as well as possible
  
  directions for future research is reported.
