“…Several researchers have studied the composition and mechanical properties of various modified bitumens (Huang and Shu 2009;Kök et al 2011;Yildirim 2007;Aflaki and Tabatabaee 2009;Aflaki et al 2014).…”

This work focuses on the ageing behavior of asphaltite modified paving bitumens. The addition of asphaltites in soft petroleum bitumens gives harder binders which are suitable for the production of high modulus bituminous mixes used in pavements construction. Such techniques are already used in several projects. However it is not known how asphaltite modified binders behave during ageing. In general, bitumens get harder, more elastic and consequently more brittle during ageing. In order to evaluate the ageing incidence we have studied the evolution of several mechanical properties of asphaltite modified bitumens during ageing. The evolutions of asphaltite modified bitumens during aging are compared

“…The Gilsonite additive increases resistance to permanent deformations at high temperatures, and also increases the G * /sin(δ) parameter of asphalt binders modified with this additive before and after the ageing process. Hot mix asphalt modified with the Gilsonite additive are characterized by increased stability and a lower range of permanent deformations, which translates into a higher resistance to rutting while unimpaired resistance to fatigue cracking and low temperature cracking is retained [32,33,34].…”

The article describes and illustrates natural asphalts according to the classification due to the solubility of carbon disulphide. The review of bitumens and the sources of their acquisition aims to systematize knowledge on this subject in terms of practical application. Exemplary applications on an industrial scale, discussed natural asphalts with particular emphasis on their use in road construction have been presented.

“…Dating back to many years ago, asphalt binder is still used for producing asphalt concrete, and it has been known as the most common construction material for paving the roadways [1]. However, researchers are still continuing to develop higher-quality asphalt binders resulting in more sustainable and resilient flexible pavements [2][3][4][5]. The overall performance of asphalt mixture is highly dependent upon the asphalt binder's intrinsic properties [6,7].…”

This study set out to evaluate the influence of carbon black (CB) on the rheological properties and activation energy of asphalt binder at high service temperatures. The rheological performance of virgin and modified asphalt binders are investigated using three evaluation approaches: (1) Superpave specification parameter (G*/sinδ), (2) multiple stress creep recovery (MSCR) test, and (3) interaction model for computing zero shear viscosity (ZSV). Moreover, the Arrhenius model was used to quantify the activation energy (E f ) of virgin and CB-modified asphalt binders. The result of this study reveals that modifying asphalt binder with up to 10% of CB, by weight of the total asphalt binder, enhances the elastic behavior (R%) and decreases the non-recoverable creep compliance (J nr ) of asphalt binder at high temperatures. Moreover, according to this study, the ZSV index can describe successfully rutting resistance of asphalt binder when compared with MSCR and Superpave rutting specification parameter. Besides, it was indicated that CB-modified asphalt binder has a high fluid resistance as more thermal energy was required for overcoming intermolecular force between molecules.
