Description: Miscellaneous Paper
Abstract: One of the shortcomings of asphalt concrete (AC) overlays is the eventual occurrence of reflective cracking. Reflective cracks are fractures in the overlay that occur because of excessive movement of cracks and joints in the underlying pavement layers. Without some form of prevention or reduction of these reflective cracks, early deterioration of an asphalt overlay can occur. The asphalt rubber and geotextile interlayers are used to prevent and reduce reflective cracks and to act as a waterproofing medium when overlaying structurally sound AC and portland cement concrete (PCC) pavements with AC in warm, dry climates. The description, applicability, benefits, limitations, costs, recommended uses, and location of demonstration sites for asphalt rubber and geotextile interlayer technology are discussed.
