“…The slopes of both pyrolytic products are steeper than those representing bitumen. This is contrary to our expectations because Airey et al discovered in their research that synthetic binder has a flatter slope, compared to the curve for bitumen derived from crude oil [26]. A steeper slope means smaller temperature range of applicability, but at the same time the binder is more susceptible to the change of viscosity with temperature [27].…”

New binders are produced in order to reduce dependence on crude oil. This study aims to evaluate pyrolytic products and their blends with bitumen, as a possible substitution for bitumen. Bitumen of the penetration grade 70/100 was used as a matrix for the blends. Standard test were conducted in order to determine mechanical properties of the reference bitumen, pyrolytic products, and their blends. The results obtained during this study indicate that pyrolytic products can be used as a substitution for bitumen originating from crude oil or, in proper proportions, as an additive to that bitumen. Analiza mogućnosti primjene produkta pirolize kao zamjene za bitumen u asfaltnim mješavinama Nove vrste veziva se proizvode kako bi se smanjila upotreba sirove nafte. Ispitivanje je provedeno s ciljem analize proizvoda pirolitičkog spaljivanja i njegove mješavine s bitumenom, kao moguće zamjene za bitumen. Kao kontrolni bitumen korišten je cestograđevni bitumen 70/100. Uobičajenim ispitivanjima utvrđena su mehanička svojstva kontrolnog bitumena, proizvoda pirolize i njihovih mješavina. Rezultati ispitivanja pokazuju da se proizvod pirolize može primjenjivati kao zamjena za bitumen ili, u prikladnom omjeru, kao dodatak bitumenu.

“…The softening point is also an indication of the point in time when the road pavement will likely deform due to high temperatures. The temperature sensitivity of asphalt is relatively low when the softening point is high [26]. The softening point results are presented in Table 4.…”

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.

“…Since the adoption of the Kyoto protocol, global efforts have been made to modify energy consumption practices in accordance with more stringent environmental guidelines, to limit production of greenhouse gases, and reduce consumption of petroleum products. Among the many studies that have been conducted to address these issues are studies on the use of renewable natural resources and synthetic adhesive binders as replacements for asphalt binders [4][5][6][7] . Another method that has gained popularity within the asphalt industries is the use of warm-mix asphalt (WMA).…”

This paper describes the rheological properties of PG64, PG70, and PG76 asphalt binders blended with different Sasobit ® contents. The rheological properties of the Sasobit ® -modified binders were characterized after being subjected to different aging conditions using the dynamic shear rheometer (DSR) and rotational viscometer (RV) according to Superpave TM test protocols. The results indicated that the characterization of aging in terms of the Aging Index (AI) depends on the rheological property of the asphalt binder selected for use in evaluating aging, the amount of Sasobit ® , the binder type, and the temperature range. Linear relationships between failure temperatures of unaged and short-term-aged asphalt were observed for three binder types. Design charts were developed to select the appropriate Sasobit ® content as a function of temperature, taking into consideration the stiffening effects of Sasobit ® , using the Superpave TM fatigue factor and asphalt mix construction temperatures.
