Distress Criteria for Pavement Systems
This report presents results of a study to select appropriate pavement distress criteria to be used for nondestructive airfield pavement evaluation. Only load-related distress criteria were included in this investigation, and all environmental considerations were excluded. A field testing program, including determination of physical characteristics of pavement materials and pavement deflection measurements under different loading conditions, was implemented. Low-frequency, steady-state vibration tests were used to generate deflection readings. High-frequency, steady-state vibration tests were used to determine the elastic properties of pavement layers by wave propagation techniques. Equipment used included the U.S. Army Corps of Engineers Waterways Experiment Station and the U.S. Air Force Civil Engineering Research Facility vibrator-loading devices. Deflection measurements were compared and analyzed. Theoretical analyses were performed relating field results to pavement design and evaluation theories. The relationship between load repetitions to either (a) compressive strain in the base, subbase, or subgrade; or (b) tensile strain in the top pavement layer, was selected as the most appropriate airfield pavement distress criteria. A tentative airfield flexible pavement evaluation procedure, compatible with the selected distress criteria, is proposed. (Author)
