Arabani, M. / Jamshidi, R. / Sadeghnejad, M.

Highlights • There is a good relationship between the predicted and measured rutting after parameters adjustment. • Model can properly predict rutting behavior of glasphalt mixture in different stresses. • Glasphalt model shows a lower rutting for the testing condition ranges of this paper. • Results show that glass cullet has positive effects on rutting behavior of asphalt samples.

Abstract In recent years, many researches are carried out to investigate the effect of waste glass on dynamic properties and mechanical performance of Hot Mix Asphalt. In these researches, the improvement of behaviors of glasphalt in compare with conventional asphalt is illustrated against rutting performance and permanent deformation which are the most important damages that occur during the service life of asphaltic pavements. The scope of this research is to simulate rutting performance of glasphalt pavement and comparison with conventional. To achieve this goal, ABAQUS software is used and outputs of model are compared with the experimental observations. The results of this research show that presented model can properly characterize rutting behavior of glasphalt mixtures. By comparison of glasphalt and conventional models, it conclude that glasphalt pavement have lower than rutting in compare to conventional at different stresses and number of passes.
