Özet

Within the context of this study, the deformation behaviour of multi layered highway road embankment consist of asphalt concrete supported by the underlying base and subbase layer under repetitive wheel load were analysed using finite element methodology. Plane strain finite element analyses were carried out by using Plaxis software to calculate rutting behaviour of embankment. Asphalt concrete was modelled using linear elastic model whereas hardening soil model with small-strain stiffness (HSsmall) was used to examine deformation behaviour of base, subbase and subgrade layers due to its capability to model stress dependent stiffness, unloading-reloading behaviour and hysteric damping.
