Abstract: For performance prediction, it is important to know whether a pavement structure will experience progressive accumulation of permanent deformation leading to a state of incremental collapse, or if the increase of permanent deformation will cease, resulting in a stable and elastic response. For such predictions shakedown and limit analyses provides significant advantages over other forms of analysis when a global understanding of deformation behaviour is required. In this paper, a numerical technique, based on the Linear Matching Method, of Ponter and Engelhardt [1], is apply to the investigation of the long-term behaviour of pavement structures under repeated wheel loads of different magnitudes. This method is a general upper bound method capable of providing the minimum upper bound shakedown limits associated with a class of possible displacement fields described by a finite element mesh. The proposed formulation is first verified using a homogeneous isotropic half-space and then applied to a two-layer pavement. The variation of shakedown limits with material properties and layer thickness is investigated.
