• Abstract:
  In 1993, ODOT constructed test sections on State Route 4 (SR-4) to study the effectiveness of Breaking and Seating (B/S) as a rehabilitation strategy for retarding reflection cracking in asphalt overlays of jointed reinforced concrete pavements. After nine years service, the break and seat test sections displayed relatively few reflection cracks. In 2004, however, a significant number of transverse cracks were observed to have occurred directly over the underlying joints in the concrete layer. To determine the implications of this recent cracking on the expected performance and maintenance requirements of future break and seat projects, an in-depth forensic analysis of the nature and mechanism of the cracking was needed.
