STABILITY OF MULTILAYER SYSTEMS UNDER REPEATED LOADS

Multilayer systems such as pavements and railroads are subjected to repeated traffic loads of varying magnitude and number of repetitions. The accumulation of plastic strains in a given system may increase under repeated load applications, leading to a state of incremental collapse, or plastic strain may cease to increase with time, resulting in a stable response or shakedown condition. An improved numerical method for the application of shakedown theory to multilayer systems is presented. The proposed method is used to analyze two-layer pavements with varying geometry and material properties. Fatigue and shakedown analyses are also performed for two-layer systems consisting of a cement-treated layer and an asphalt concrete layer overlying a subgrade. Results of analyses are compared and discussed in relation to the design of such systems.
