Investigation of Low Temperature Properties for Ultraviolet Radiation Aged Bitumen and Mixture
Asphalt 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 and mixtures 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. From the results, after the addition of layer clay powder, the anti-aging properties is greatly improved and low temperature properties can be better maintained compared to base asphalt.
