Layered Pavement Systems: Analysis Related to Design Procedures
Theoretical and experimental studies related to the development of a thickness design procedure for airfield pavements are discussed. The pavement is treated as an elastic layered half-space and the moduli of elasticity of the paving materials as the primary design factors. Equations and influence charts derived from the application of elastic theory to two- and three-layered systems are used to interpret the experimental plate-bearing data. Values of the modulus of elasticity are presented for three base materials. It is shown that the modulus of elasticity depends upon the quality of the base, its depth and density, and the stiffness of the contiguous subgrade. The principal failure modes observed in flexible pavements and the suitability of the triaxial test as an adjunct to pavement design are discussed. A suggested revision in the current Navy pavement design procedure is presented. Recommendations for continued research related to layered theory pavement design are also included. A thickness design criterion for portland-cement-stabilized sand bases is presented as part of this study. (Author)
