The application of the concentration index to pavements is illustrated. The problem with the design of flexible airfield pavements under newly developed jumbo-jet aircraft, as represented by the Lockheed C-5A Galaxy and the Boeing 747, is discussed. These aircraft are equipped with extremely large multiple-wheel landing gears. It is found that the CBR design equation can be used to evaluate the pavement performance under multiple-wheel gear assemblies when the equivalent single-wheel load (ESWL) is computed by the concentration index method. The concentration index is approximately independent of the load, gear configuration, and soil strength but varies with the depth.
