MULTIPLE-WHEEL HEAVY GEAR LOAD PAVEMENT TESTS. VOLUME IV. ANALYSIS OF BEHAVIOR UNDER TRAFFIC

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)
