This paper is to study the mechanism of aging on the rheological properties of the asphalt and make correlations with the actual field behavior of the binder. The effects of ageing on rheological properties of asphalt has been studied by Dynamic Shear Rheometer(DSR). Significant differences of rheological properties and composition were observed between fresh and aged asphalt. The results show that aging at low temperature increases the complex modulus of asphalt, but has little effect at high temperature.
This paper is to study the mechanism of aging on the Rheological and Chemical Investigation of the bitumen and make correlations with the actual field behavior of the binder. The effects of ageing on rheological properties of asphalt has been studied by Bending Beam Rheometer(BBR). The objective of conducting these tests is to evaluate the performance of the bitumen in an aged and unaged states in relation to the effects of traffic speed and/or pavement temperature, traffic volume (number of load repetitions), and (thermal/load) cracking behavior.
