“…Asphalt constitutes only a small but crucial part of any paving mix. It also influences pavement performance at low and high field operating temperatures [5][6]. Due to continuously increasing traffic volumes, axle loads and the effects of temperature cycling, pure asphalt pavements are subjected to stress cracking and rutting.…”

Abstract. Nowadays, most of asphalt used in pavement construction is produced from petrochemicals through refining process of crude oil. When evolves with time, asphalt become stiffer and brittle due aging process. In this paper, the rheological effect of short-term and long-term oxidative ageing of asphalt binder modified with montmorillonite (MMT) was studied using Superpave™ rotational viscometer (RV), dynamic shear rheometer (DSR) and Fourier transform infrared (FTIR) instruments. The results indicate the addition of MMT increased the viscosity. Based on dynamic mechanical analysis with DSR, MMT modified binder has a potential to increase rutting and fatigue resistance. In terms of FTIR test, it appears that the chemical bonding had changed in the asphalt binder before and after RTFO and PAV aging which suggest that the additional of MMT could delay the aging process.

“…These findings are reasonable and the relationship between the predicted and measured permanent deformation values from regression analysis can be used to develop models effectively. It is revealed that the relationship of selected dependent and independent variables can affect the pavement performance [19].…”

Asphalt binder plays an important part in determining many aspects of road performance. However, the rheological properties of asphalt binder are very complex and the parameters depend purely on the viscosity, various loading time and temperature. Therefore, relationship study on asphalt binder rheological properties and asphalt mixture is vital to predict the performance of the mixture. This paper evaluates the relationship between rheological asphalt binder and asphalt mixture performance containing nanopolymer modified binder. Five sets of asphalt binder rheology were tested to determine their viscosity, effect of short term and long-term aging using the dynamic shear rheometer (DSR). The asphalt mixtures performance test was then conducted to evaluate the permanent deformation of the mix. Findings from this study indicate that the rheological properties of asphalt binder acts as indicator for the asphalt mixture performance. The G*/sin δ and viscosity of the asphalt binder significantly agree with the resilient modulus and rut depth results obtained. The dependent (resilient modulus at 40 o C and rut depth) and dependent (G*/sin δ and viscosity) variables show that these variables significantly affects each other. An effective prediction models can also be developed according to predicted and measured permanent deformation values.

“…Regarding the aging performance, short term and long term aging tests are carried out using the Rolling Thin Film Oven Test (RTFOT) and the pressure aging vessel (PAV) respectively, following the standard practice outlined by American Association of State Highway and Transportation Officials (AASHTO) [34]. The aging properties of asphalt binders are normally characterized by measuring physical and rheological properties (e.g.…”

Raising the prices of crude petroleum is affected to good performance for the asphalt paving and has encouraged to modify or replace asphalt bitumen. Increasing numbers of commercial vehicles and increase axle load that this trend will continue yearly. Design, construction and maintenance facilitate asphalt roads to provide the high standards of safety and comfortable but certain areas of a road are higher stressed than others. For that reason road paving industry is interested in utilizing alternative and sustainable binder materials for modified asphalt to improve the production, placement and performance of asphalt mixtures. However, sources of materials should be considered economically and environtmentally viable after applied in pavement. According to previous research, that has been developed that non crude petroleum binder derived from the production of bio-oil through fast pyrolysis of biomass. The main source of bio-oil can be contributed from biomass industry or renewable organic industry such as timber waste, oil palm waste, rice husk; coconut trunk fibers, municipal waste and sugar cane waste. Alternatively, the bio-oil can be as substitute material as modification of asphalt. This paper presents a review on the source, characteristic of bio-oil and the effects of bio-oil on the properties of asphalt bitumen.
