  • 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.
