Abstract : The report describes a finite-element procedure for analyzing multilayered concrete airfield pavements. An 'equivalent plate' theory is used to account for the increased stiffness provided by a stabilized base or a structural overlay. The stiffness is also adjusted to provide for the effects of various bond levels developed between the pavement layers. The finite-element pavement model was developed to aid the study of airfield-pavement interaction and especially to help analyze surface deformations resulting from multi-wheel aircraft loads. Pavement joints are given finite dimensions and treated as separate entities to permit more accurate determination of stress at an edge in a jointed pavement. Subsoil material can be modeled as a linear elastic, non-linear, or non-linear viscous material. (Modified author abstract)
