An approach is described that is used to identify to what degree Michigan's concrete pavements are affected by materials-related distress (MRD) and to determine what distress mechanisms are at work. The approach taken includes a network-level visual assessment and detailed visual inspections, field sampling, and laboratory analyses on 14 selected projects to determine the distress mechanisms. It is concluded that although the majority of Michigan's concrete pavements are unaffected by MRD, a significant percentage of the concrete pavement network has distress manifestations consistent with the occurrence of MRD. These manifestations included staining in the vicinity of joints and cracks, D-cracking, joint-crack deterioration, progressive map cracking with exudate, scaling, and corrosion of embedded steel. Each pavement section was visually assessed and then tested using a falling weight deflectometer. Field air permeability measurements were also made, and core samples were removed from the pavement to be analyzed in the laboratory. It was found that the presence of MRD affected both the mechanical and the microstructural properties of the pavement concrete. Further, the laboratory analysis determined that a number of MRD types are at work in some of Michigan's concrete pavements, including aggregate freeze-thaw deterioration, corrosion of embedded steel, and alkali-silica reactivity. This work also found that dedolomization of certain carbonate aggregates and sulfate attack may pose a problem. With this knowledge, the Michigan Department of Transportation is better able to address the cause of distress when selecting repair options and to prevent MRD from affecting future concrete pavements.
