Abstract: The maintenance need of cracked highway structures has relied upon bottom-up mechanistic design models for asphaltic pavements. A badly cracked pavement will normally require a major maintenance program involving removal and reconstruction of the highway. However, the repair of top-down cracked pavements can generally be confined to the replacement of the upper portion of the pavement structure with new materials. The correct identification of the type of cracking that is occurring in pavements will consequently make a significant impact upon the cost of rehabilitation of pavement sections. In addition, the selection of materials for the top-down cracked pavement is likely to be significantly different from those considered for deep, thick asphalt pavement sections. The aspects of material behaviour for top-down cracking are poorly understood. A need was identified to develop a method of pavement evaluation that will correctly identify the type of pavement distress and materials selection for rehabilitation.During 2002 three surface cracked pavements in Indiana in United States were evaluated. This involved a visual survey, Falling Weight Deflectometer (FWD) tests and a full laboratory-testing program to define rheology and fracture properties of the materials. A conceptual analysis scheme with an implementation approach is discussed along with additional research recommendations to verify the approach taken.
