The research discusses roads rehabilitation using foamed bitumen,which is a relatively new method and hasn’t been used in Syria yet due to the lack of the needed labrotory equipments ,and that’s why the main aim of the research is to develop a model to stimulate the labrotory experiments needed to evaluate the performance of the rehabilitated pavement (surface deflection – strain ). The model was developed using the finite elements method with the help of ABAQUS modelling software.
