Description
Summary:This paper focuses on the numerical modelling aspects of cyclic loading on reinforced unbound pavements under plane-strain condition. The effect of reinforcing elements on the displacement and stress quantities, their implications for some design assumptions, and the adequacy of the bar and solid elements for reinforcement representation are also investigated. The nonlinear behaviour of pavement materials under cyclic loading is accounted for, and results are given for: axial forces in the reinforcement; shear stresses within the aggregate and subgrade layers; and the wheel-load/displacement response.
