Performance of asphaltic concrete incorporating SBR subjected to aging

The influence of styrene butadiene rubber (SBR) on asphaltic concrete properties at different aging condition presented in this study. These aging conditions are named as un-aging, short-term and long-term. The conventional asphalt binder of penetration grade 60/70 was used within this work, modifie...

These aging conditions are named as un-aging, short-term and long-term. The conventional asphalt binder of penetration grade 60/70 was used within this work, modified with styrene butadiene rubber (SBR) at four different modification levels namely 0%, 1%, 3%, and 5% by weight binder.

The result also showed that the stability, resilient modulus and dynamic creep tests under long term aging is the highest among than that of the short term and un-aged.
