Water has long been recognized as a major contributor to pavement failures. To lessen the potential for damage due to water, the US Army Corps of Engineers established drainage criteria for bases and subbases in airfield pavements. Since the establishment of the drainage criteria, the use of dense-graded aggregate has become the most used material type for airfield pavement bases. Laboratory studies conducted in the late 1960's indicated that the dense-graded bases were almost impermeable and would not meet the drainage criteria. Bases constructed from a uniform size aggregate (an open-graded base) would provide the required permeability but do not have the stability of a denser graded base. A literature review and field survey on the use of open-graded bases and the results of a pilot test section to illustrate the structural capabilities of open-graded bases and follow-up on some ongoing studies are included in this report.
