Asphalt material is visco-elastic material, which is sensitive to temperature and such phenomenon can result in affect to super-structure of concrete trackbed systems under various temperature loads. Consequently, the key objective of this research is to evaluate the performance related to stress changes of wide sleepers on asphalt-concrete trackbed systems corresponding to temperature changes. The range of temperature to represent the season is 60℃∼-10℃ and the numerical analysis was conducted in ABAQUS
