Abstract
The interface bond between layers plays an important role in the behaviour of pavement structure. However, this aspect has not yet been adequately considered in the pavement analysis process due to the lack of advanced characterizations of actual condition. In many pavement design procedures, only completely bonded or unbounded interface between the layers is considered. For the purpose of better evaluation of the asphalt pavement behaviour, the present work focused on its investigation taking into account the actual interface bonding condition between the asphalt layers. The interaction between pavement layers was taken into account by introducing a horizontal shear reaction modulus which represents the interface bonding condition for a given state. The analytical solution was then implemented in a numerical program before doing forward calculations for sensitivity analysis which highlights the influence of the interface bonding conditions on the structural behaviour of asphalt pavement under a static loading.
