“…At the temperature of 135 • C, the viscosity of all binders were lower than 3.0 Pa•s, which satisfied the Superpave standard specification. This result was consistent with previous work by Ezzat et al [30], Alhamali et al [44], and Santagata et al [45]. The resistance to permanent deformation of bitumen may be partly due to increased viscosity, which results in a higher stiffness at elevated temperatures.…”

Due to storage stability drawbacks of polymer-modified bitumen (PMB), this study investigated the storage stability and physicochemical performance of Styrene-Butadiene-Styrene (SBS) asphalt binders (herein PMB) modified with Silicone surface-treated nanosilica (SNS). Dosages 0% (control), 1.5%, 3% and 5% SNS powder were added to PMB to prepare modified binders. Hot storage, Viscosity, Multiple Stress Creep Recovery (MSCR), Scanning Electron Microscopy (SEM), Fluorescence Microscopy (FM), Linear Amplitude Sweep (LAS), Fourier Transform Infrared (FTIR), and Proton Nuclear Magnetic Resonance (1H-NMR) tests were conducted using modified binders. The study found that adding nanosilica powder to PMB improved storage stability, increased viscosity and complex modulus, and reduced rutting of binders. However, this bitumen modification was not beneficial to fatigue cracking. The performance improvement was because of the interaction between the polymer and nanosilica, creating a new polymer-nanosilica network which lowered the dynamics around the SNS particles, thereby reducing phase separation. Further, the Silicone Si–O–Si backbone bond present in SNS modified asphalt binder reduced temperature sensitivity thereby preventing thermal degradation at high storage temperature. Nanosilica modified binders presented well-dispersed nanosilica particles in the asphalt matrix. The modification mechanism was predominantly physical. Overall, the study concluded that nanosilica improves storage stability, rutting, and morphology of PMB binders.

“…In order to measure the tensile feature of asphaltic materials and to show the cohesion of the asphalt cement binder, a ductility test is also performed on the asphalt samples. Asphalt binder with a high ductility value is generally considered to have good low-temperature service efficiency and better recovery ability during stress application [17]. The test was done according to the standard ASTM D113 [20].…”

“…Also, it can be seen that the addition of WPP combined with NS increased the ductility values as the concentration of nanosilica increased. This increase can be explained by that the addition of NS/WPP contributes to an improvement in asphaltic flexibility that represents the ability to recover after loading [17].

“…Several studies found that nanosilica powder has been used to reinforce polymers [15]. Nanomaterial composite/polymer modification reduced both the quantity of nanomaterial and polymer and at the same time, enhanced the compatibility of polymers with bitumen [16], improved the rheological properties, and decreased rut depth [17].…”

Recently, polymer -nanocomposites were used to manufacture durable asphalt mixtures to replace the polymer modified binder, because of the remarkable properties and unique features of nanomaterials compared to conventional materials, such as their wide surface area and small dimensions, making it possible to be utilized as an additive for asphalt paving. Nanosilica particles (NS) are one of the latest minerals which likely integrate useful characteristics, such as huge surface area, good distributions, high absorption levels, high stability, and a high level of purity. Therefore, this paper is interested in studying the characteristics of nanocomposite-polymer modified asphalt. In laboratory work, a pure asphalt 60-70 penetration grade, has been modified separately with waste polypropylene polymer (WPP), and nanosillica composite polypropylene (NS/WPP) at different concentrations. As a result, two modified binders: waste polypropylene polymer- modified asphalt (WPP-MA), and nanosillica composite polypropylene modified asphalt (NSCPMA) were obtained. Traditional asphalt binder tests were performed for pure and modified binders such as penetration, ductility, flash and fire point test, softening point, and rotational viscosity. Also, storage stability test has been conducted to ensure the storage stability of binders at high temperatures. The results showed an improvement in physical properties and increase in mixing and compaction temperature due to the increase in stiffness of (NSCPMA). The results also indicated that the nanosillica composite polypropylene modified asphalt binders have good storage stability at high temperatures.

Due to their excellent physicochemical and structural characteristics, aluminum oxide (AL 2 O 3 ) nanoparticles (AlNPs), a family of metal oxide nanoparticles, offer a variety of biological uses. Bitumen binds a high percentage (>95%) of inorganic macrometer-sized particles to provide a cohesive material suitable for use in road pavement. In this study, AL 2 O 3 was added to bitumen as a new bitumen modification to improve the fatigue and rutting performance of bitumen or the base cement asphalt cement (AC) at ratios of 5, 7, and 10% wt by weight of the cement AC. Rheological tests were performed on modified bitumen containing nanoparticles. An extreme learning machine (ELM) analyzes each test outcome. In this case, the properties of AC are greatly affected by the rise in AL 2 O 3 concentration. In comparison to the basic AC, the modified AC's viscosity rose by 90 and 104%, respectively. The outcomes also demonstrated the excellent compatibility and storage stability of both modifiers at high temperatures. A hot mix of AL 2 O 3 modified bitumen was utilized to produce hot cement asphalt samples, and moisture susceptibility was assessed. As a result,
