Book Description
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).

Book Description
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 Description
Flexible and rigid pavement test sections were constructed and tested to gain information on pavement and soil behavior under large aircraft loadings. These 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. The components of the instrumentation systems, their installation, and the test programs are described in this volume. (Author).

Book Description
Flexible and rigid pavement test sections were constructed and tested to gain information on pavement and soil behavior under large aircraft loadings. These test sections incorporated instrumentation systems designed to deteermine the response of the pavement structures of static, dynamic (slowly moving), and vibratory loads and to traffic by full prototype loadings. This volume covers data reduction, analysis, and the findings of the instrumentation and vibratory testing programs; Appendixes A and B contain details of instrumentation measurements for flexible and rigid pavements, respectively.
