Available in PDF, EPUB and Kindle. Book excerpt: The document presents recommended changes to Federal Aviation Administration (FAA) Advisory Circular No. 150/5320-6A, Airport Paving, relative to design and evaluation of airport pavements subject to traffic resulting from operation of the Boeing 747 and/or Lockheed C-5A aircraft. Criteria for flexible and rigid pavements were prepared in accordance with procedures developed as a result of an engineering investigation of the effects of traffic of multiple-wheel heavy gear loads.

Book excerpt: Flexible and rigid pavements were constructed and tested to obtain data on pavement and soil behavior under large aircraft loadings for use in developing criteria for evaluating and designing airfield pavements subjected to multiple-wheel heavy gear loads (WMHGL). The test sections incorporated instrumentation systems designed to determine the response of the pavement structures to static, dynamic (slowly moving), and vibratory loads and to traffic by full prototype loadings of a 12-wheel assembly (one main gear of a C-5A aircraft), a twin-tandem assembly (one twin-tandem component of the Boeing 747 assembly), and a single wheel. Analysis of static load response data from the flexible pavement instrumentation program resulted in the establishment of maximum elastic deflection and vertical elastic stress versus depth curves. Comparisons showed that the same relationships were true for static and dynamic load tests, as well as for speed tests. The findings for the rigid pavement test section indicated that the Westergaard algorithm can be used for reasonable predictio of pavement response to test loadings. The data from the instrumentation program and the traffic tests were used in the analysis of the flexible and rigid pavement test sections. The analysis resulted in a modification of the basic flexible pavement CBR design method. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Flexible and rigid pavement test sections were constructed and tested to obtain data to validate present criteria, to establish modifications to present criteria, or to develop new criteria for the evaluation and design of airfield pavements to be subjected to multiple-wheel heavy gear loads (MWHGL). The basic CBR design method was expanded and modified to obtain a method of design for flexible pavements subject to traffic by MWHGL. The recommended method reflects a reduction of existing U.S. Army Corps of Engineers (CE) thickness requirements that is especially significant for multiple-wheel assemblies in the higher operational level. Current CE evaluation and design methods for rigid pavements are based on stress in the concrete pavement as calculated from the Westergaard analysis. (Author).

Book excerpt: The instrumentation data of the multiple-wheel heavy gear load (MWHGL) tests were reduced and analyzed. By incorporating the performance of test pavements under traffic, relations between load and pavement response were established. A method was developed to compute the measured stresses and deflections of the test pavements; based on the method, the stresses and deflections can be computed for similar types of airfield pavements under different loads. Correlations were established between computed parameters and traffic performance data from the MWHGL test section as well as from many other pavement tests conducted by the Corps of Engineers. Based on the instrumentation data, the principle of superposition was found to be valid for flexible pavements. Attempts were made to reevaluate the equivalent single-wheel loads for MWHGLs by many different methods. (Author).
