This report presents the findings of a study performed to review the methodology and evaluate the effectiveness of drainage systems for airfield pavements. Official Pavement Evaluation and Condition Survey Reports were reviewed for military air bases in Continental United States and a number of foreign countries a number of airfields in the United States were inspected some with a Waterways Experiment Station team and test holes were drilled into heavy-duty pavement at three airfields. The testing consisted of measuring the in-place permeabilities of base and subgrade materials, and recording the saturation levels within pavements in relation to rainfall events. At a fourth Field Investigation site, discharges from pipes to a comprehensive underdrainage system were measured in relation to rainfall events, to develop the time-lag characteristics of the drainage system.
