“…The development of nano-materials in soil reinforcement could result in considerable benefits as these materials have shown to give significant advantages, especially in concrete technology (Al-Mansob et al 2017;Govindasamy et al 2017). Because of their unique mechanical properties carbon nanofibers (CNFs) and carbon nanotubes (CNTs) are gaining popularity as promising nanomaterials.…”

“…Although polymer-modified bitumen offers promising results, many researchers have noted a major shortcoming of the modification process, which is the compatibility issue between the polymer and bitumen (21,22) (23). According to Al-Mansob et al, (24) the incompatibility is associated with the occurrence of phase separation due to the differences in density, molecular weight and solubility between the polymer and asphalt. Lu et al, (25) further stated that the phase separation is governed by the chemical composition of the bitumen and the characteristics of the polymer.…”

The current study focuses on the effect of Acrylate-styrene-acrylonitrile (ASA)/Nanosilica (Si) modified binders on the complex modulus (G*) and rutting resistance parameters (G*/ sinδ) of Asphalt Cement (AC). Four different blends including the base binder and the polymer nanocomposites which were formed by blending 5% ASA to base binder with the addition of nanosilica at 3, 5 and 7% by the weight were the subject of investigations. Conventional and Dynamic Shear Rheometer (DSR) testing procedures were conducted as well as morphology analysis using Fourier Transform Infrared Spectroscopy (FT-IR). The rheological characteristics of AC were analysed by master curves, isochronal plots and rutting resistance parameter plots. Test results revealed that G* and G*/ sinδ of all modified samples were significantly enhanced compared to the base binder. Multiple Stress Creep Recovery Test (MSCRT) conducted at 100 Pa and 3200 Pa showed that, non-recoverable compliance was reduced and elastic recovery of modified binders were improved. Optimum concentration was found to be 5% ASA/Si composite, as further addition of polymer nanocomposite resulted in lower enhancement in the rheological properties of modified AC due to the occurrence of agglomeration between the composite and the base binder.

“…Accordingly, improved resistance of asphalt concrete to rutting. Al-Mansob et al [8] studied the effect of adding nano-alumina to bitumen and found that it has a significant hardening effect leading to both decreasing the penetration depth and increasing the softening point of the modified samples. Hussein et al [9] reported similar results for bitumen modified with ceramic waste nanoparticles consisting mainly of silica and alumina.…”

Using nanotechnology in asphalt paving has increased markedly to improve the asphalt characteristics and increase the road life, especially with the significant increase in traffic volumes. The present contribution evaluates the effects of ore nanoparticles namely ilmenite and bentonite on the engineering properties and performance of asphalt binder. The high-resolution transmission electron microscopy (HRTEM) micrograph was used to characterize the investigated nanomaterials. The nanoparticles were blended with asphalt binder with different percentages (0-5% for ilmenite and 0-10% for bentonite by weight of asphalt binder) to determine the appropriate mixing ratio that sustained the desired characteristics. Different tests were conducted to examine the properties of modified asphalt binder among which penetration, softening point, rotational viscosity, penetration index (PI) and ductility. The results of our study revealed an increase in softening point and rotational viscosity and decrease in binder penetration. Moreover, blending of variable amounts of nanomaterials with the asphalt binders has improved their physical properties compared with macroparticles blended and unmodified binders as indicated by the penetration index and ductility test. The most significant improvement in the modified binders was obtained by blending of 5% for two types of nanoparticles. Finally, the rut depth was measured by wheel track test for the modified asphalt mixture, with ilmenite and bentonite, to validate the obtained results. The results show that the engineering performance of asphalt produced from bitumen binder modified with nanoparticles is much better than conventional asphalt and such binder-modified asphalt is strongly recommended for use on site.
