Research on Low Temperature Rheological Behavior of Aging Resistant Bitumen and Mixture
Bitumen is widely used in road construction, but it is an organic mixture with complex compounds and chemical structures which will change after exposed to heat, oxygen, and ultraviolet radiation (UV) and make the physical properties worse, especially at low temperature. In this paper, different aging levels (TFOT, UV-6days) of asphalt binders with various mass ratio of layer clay powder to asphalt (0,3%,5%) were considered to investigate the low temperature rheological properties of aged asphalt binders and low temperature strength as well as fatigue properties. Dynamic Shear Rheomoter (DSR) and Universal Testing Machine (UTM) were used to evaluate low temperature properties of bitumen and mixture. The ageing evaluation shows that the ageing resistance of bitumen and its mixture is improved and this improvement at low temperature properties can be better maintained compared to base asphalt.
