Research on viscoelasticity of modified bitumen containing LDHs anti-UV aging agent

Abstract

We applied LDHs to modify the bitumen by melt blending, and studied the viscoelasticity of LDHs modified bitumen by means of dynamic shear rheometer (DSR). The creep test was used to evaluate the viscoelastic behavior. The experimental results indicated that, due to the addition of the LDHs, the viscoelastic properties of modified bitumen were superior to those of pristine bitumen. Therefore, the LDHs would be an alternative to modifiers used in the bitumen to improve the UV-aging resistance during the service of asphalt pavement.
