• Abstract:
  The research involved evaluating three surface cracked pavements during 2002 and 2003. A 500m section of I-65 North of Lafayette was chosen as the first site (designated as Site 1), an I-65 section in downtown Indianapolis was the second site (Site 2), and US-421 in Madison was the third site (Site 3). Site 1 had 11-year-old pavement, Site 2 had 12-year-old pavement and Site 3 had 4.5-year-old pavement. All these sites exhibited longitudinal wheel path cracking which was later identified as top-down cracking. All sites had excellent structural capacity indicating that the top-down cracking was confined in the pavement surface. This was confirmed by visual inspection of cores. The causes for top-down cracking in the surface layer were identified as follows: 1) non-uniformities in the material properties caused by construction practices such as segregation; 2) high in-situ air void content; 3) low amount of fines in mixtures, and 4) aging of binder. However, the study was not able to identify/verify any structural causes for top-down cracking.
