“…This consequently delay oxidative aging in the modified binder, the reduction in aging can be attributed to the large pore size, the huge surface area of interaction of nanosilica particles and hydroxyl groups presence on the surface of nanosilica, because the oxygen atom presence in the hydroxyl groups on the surface of nanosilica has higher electronegativity than the hydrogen atoms. This makes it more easily to form hydrogen bonds with aromatic sheets in polar aromatics and asphaltene molecules in the bitumen and that type of interactions decreases the proneness to oxidation of polar aromatics and asphaltene molecules, which have both shown to be quite prone to oxidation, a similar phenomenon was also observed by Fini et al (2015).…”

“…Nanosilica composites recently attracted scientific research interest due to its greatest benefit of reduction in the cost of production and excellent performance features (Yusoff et al, 2014). Nowadays, due to high surface area and stability of nanosilica, it is widely used as inorganic filler in polymers and bitumen binder to enhance properties of polymers and bituminous binder materials (Fini et al, 2015;Yang and Tighe, 2013). Nanosilica becomes very attractive for application in bitumen modification, because the surface of nanosilica is more chemically active with high polarity unlike other nanomaterials (Yao et al, 2012;Fini et al, 2015).…”

Nano silica has strong surface free energy and its interface atoms are arranged in a disordered manner which allows for these atoms to be bonded strongly to other outside atoms by external forces (Fang et al, 2013).…”

Performance of bituminous binders in terms of rutting and fatique is known to be related with rheological characteristics of asphalt binders. To enhance the rheological properties of binder, a modification using composite polymer and inorganic nanosilica becomes recognized as it highly improves the flow and deformation of the modified binders. This study investigates the application of polyethylene polymer and inorganic nanosilica for enhancing rheological properties as well as the oxidative aging resistance of asphalt binders. Conventional and Superpave binder test techniques. Using dynamic shear rheometer (DSR) was used to investigate the performance and rheological behaviors of the nanocomposite-modified binders. Changes in chemical bonding and morphological properties due to nanosilica were also investigated using Fourier transform infrared spectroscopy (FT-IR) and field emission scanning electron microscopy (FE-SEM). Nanosilica was added into polymer modified bitumen at different percentages (1% to 6%) by weight of bitumen binder. Results of the investigations show that composite nanosilica/polyethylene modified binders will not undergo phase separation during storage due to improved viscoelastic properties. The Superpave rutting parameter shows that nanosilica modified binders have higher resistance to permanent deformation both before and after rolling thin film oven (RTFOT) aging. FE-SEM and FT-IR investigation shows that nanosilica modified binders are less susceptible to oxidative aging hardening.

“…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.

We report on the preparation of nanocomposites using epoxy and vinylester blend in which nanoiron filler was dispersed to evaluate the mechanical performance. Different weight ratios viz.1,2,3,4,5 & 7wt.% of nanoiron particles were dispersed into the matrix to prepare different systems to evaluate the optimization of performance. Nanoiron was also prepared by chemical reduction method and nanocomposites were prepared by hand layup process. Three blade Mechanical stirrer and ultra-sonicator was used while preparing the modified to keep the non-homogeneity nanoparticle at bay. Mechanical properties such as hardness, tensile strength, flexural strength, impact strength and compression strength properties were performed. Nanoiron particles functionalization nepotisms the fabrication composites through the remedial temperature at low as associated to the as-synthesised nano particles occupied vinylester nano composites. Mechanical property values improved owing to the standardized nanoparticle chemical bonding and spreading between vinylester matrix and nanoparticles. Then the combination nanoiron particles into the vinylester resin matrix it becomes magnetically harder. Machines generated mechanical property values were compared and analysed with system generated software analysis of variance (ANOVA) values. Machine values and ANOVA values were measured for the specimens of epoxy+vinylester+nanoiron, where the nanoiron is varying viz. 1, 2, 3, 4, 5 and 7 wt.%.
