Abstract : A previous interim report presented the results of a literature review investigation geogrid reinforced base courses for flexible pavements for light aircraft and the design of a geogrid test section for field testing the validity of potential geogrid reinforcement results. This report describes the construction of the field test section, the behavior of the test section under traffic testing using a 30,000 lb single tire load, the data collected, laboratory tests that were conducted on the various geogrid products used in the field test section, and development of design criteria for geogrid base reinforcement for flexible pavements for light aircraft. Test results verified the validity of geogrid reinforced base courses for flexible pavements for light aircraft. A geogrid reinforcement product equivalent to the SS-2 geogrid used in the field tests can reduce the total pavement design thickness. The geogrid performance is a function of depth of placement. The thickness reductions range from approximately 40 percent for unreinforced pavement thicknesses of 11 in. to 5 percent for 30-in.-thick pavements....
