The effect of aging on asphalt mix

Road pavements like other civil infrastructures have a service life. Asphalt pavements get aged and become weaker. Bitumen plays a key role in aging of asphalt. In previous studies, bitumen aged separately and then it added to the asphalt mixture while in reality bitumen ages within asphalt mixture....
