Design of Flexible Airfield Pavements for Multiple-Wheel Landing Gear Assemblies. Report No. 2: Analysis of Existing Data
This study was conducted for the purpose of re-evaluating the current, tentatively adopted methods for resolving the existing single-wheel design criteria for flexible airfield pavements into criteria for multiple-wheel assemblies. Results of tests on the first multiple-wheel test section indicated that the current method yields design criteria for pavement and base thicknesses that are slightly on the unconservative side. All available data that might provide means of comparing the effects of single and multiple loadings were reviewed and a new analysis was made. Both stress and deflection effects were examined wherever possible. A proposed alternate theoretical means of resolving well-established single-wheel design criteria to give valid multiple-wheel criteria was developed. This alternate method of resolution is based solely on equivalent deflections, and appears to give somewhat better results than the tentative method now in use. The method has the distinct advantage of being capable of extension to any assembly configuration without additional assumptions.
