• Abstract:
  The objective of the study was to evaluate top-down cracked pavements and assess their structural capacity as well as study in-place materials to propose the best identification of distress type, material selection, and rehabilitation methods to be used in Indiana. Research involved evaluating three surface cracked pavements during 2002 and 2003. A 500 m 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), andUS-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. these sites exhibited longitudinal wheel path cracking which was later identified as top-down cracking. The research was carried out by conducting visual surveys, Falling Weight Deflectometer (FWD) testing, and coring the cracked and non-cracked pavement areas. Cores were first inspected and then subjected to a full laboratory-testing program to measure rheology and fracture properties of the binders used in the surface mixtures. Then, the measured material properties were utilized in a Layered Elastic analysis program to investigate stresses and strains in the top of the pavement surface.
