Impact of structure, material properties, temperature curling, and trafficking on load transfer efficiency
… on load transfer efficiency of rigid airfield pavements. The current FAA mechanistic design procedure for rigid pavements assumes constant stress-based load transfer efficiency (LTE (S)) of 25% at the joints. The design procedure assumes the material properties remain constant throughout the …

Study of load transfer efficiency of airfield rigid pavement joints based on stresses and deflections
… also determined using 2D and 3D-finite element analysis programs. The pavement configuration and the aircraft gear similar to those at NAPTF was simulated in a 2Dfinite element program JSLAB and LTE (S) under static load was determined and compared with that obtained under the moving loads. …

Verification of the dissipated energy based fatigue model using field data
… can be limited to the top layer in perpetual pavements through the use of a very thick surface layer or a binder-rich intermediate layer. To achieve this goal, tensile strains at the bottom of the top hot-mix asphalt (HMA) layer must be limited to below a certain value known as the fatigue …
