Analyze the rheology of recycled asphalts used by three rejuvenators：R1、R2、R3，the study of recycled asphalt's rheological behavior adopt BBR(Bending Beam Rheometer) and DSR(Dynamic Shear Rheometer). From the result of experiment：the usage of rejuvenator reduce the asphalt ability of anti-tracking under high temperature, some of them can even recover to the level of fresh asphalt；the mix of rejuvenators improve largely the asphalt ability of resistance to fatigue and the ability of anti-cracking under low temperature.

Rheometer Test

The influence of ultraviolet (UV) ageing on complex modulus, phase angle and low-temperature fatigue factor was studied by dynamic shear rheometer test. The ageing degree of the bitumen was evaluated by the rheological parameters. The results show that UV ageing causes an increase in complex modulus and fatigue factor, as well as a decrease in phase angle, indicating that the bitumen becomes more elastic after UV ageing process and is apt to crack at low temperatures. Different bitumen exhibits diverse changes in the rheological parameters after UV ageing, which is much dependent on the sources of bitumen.

The aim of this paper is to examine the effects of ground plastic pipe wastes on bitumen. For this purpose, three modified bitumen samples with modifier contents of 2%, 4%, and 6% along with pure bitumen were prepared and tested. To understand the effect of modifier on bitumen, conventional bitumen tests, rotational viscosity tests at 135 °C and 165 °C, dynamic shear rheometer tests at three different frequencies that represent three different traffic speeds, and bending beam rheometer (BBR) test were performed. The BBR test results showed that resistance of pure bitumen to low-temperature cracking increased by using additives up to 4%. Based on the results of this study, it can be said that waste plastic pipes can be used as modifier for the bitumen binder. The 4% additive showed the best performance.

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.

Analytical Approaches

The low-temperature properties of asphalt binder have attracted attention in recent years thanks to an increase in the use of reclaimed asphalt pavements (RAP). Traditional methods to evaluate the low-temperature properties of the binder require a large amount of binder that needs to be recovered from RAP samples for testing with a Bending Beam Rheometer (BBR). To economize on sample size for RAP materials and also for emulsion residues, previous researchers have explored the potential of using a 4 mm diameter specimen with a Dynamic Shear Rheometer (DSR) in lieu of the BBR. To compare results from frequency sweep tests conducted using the DSR with results from the BBR, data from the former need to be converted to time domain and subsequently from a shear load response to an axial load response. Previous research studies have developed methods to accomplish these two conversions to compare data from the DSR with data from the BBR. The objective of this study is to examine some of these methods from the literature and elsewhere based on the principles of linear viscoelastic interconversion using a set of 11 different binders. Results using different analytical approaches from this study show that the DSR has good repeatability and verify that it can be used as a surrogate for the BBR to determine low-temperature properties, while exercising some caution with some of the assumptions related to Poisson’s ratio.
