“…Investigations have not yet reached full scale implementation due to uncertainties over the actual cost-effectiveness of nano-reinforcement and as a result of several practical production issues which still need to be addressed. Nevertheless, according to studies documented in literature, the most promising products which have been considered for such applications are by far nanoclays and carbon nanotubes (Yang and Tighe 2013).…”

The experimental investigation presented in this paper focused on storage stability of bituminous binders containing nano-sized additives. Several blends were prepared in the laboratory by combining three base bitumens with two different types of nanoclays and one type of carbon nanotubes at various dosages. A technique based on the combination of simple shear mixing and sonication was proposed to achieve adequate dispersion of nano-particles in bitumen. Capability of materials to withstand segregation phenomena was evaluated by means of viscosity measurements performed on samples derived from simulative laboratory storage tests. Results obtained in the study revealed that high-temperature stability of nano-reinforced binders is dependent upon physico-chemical properties of base components, thus highlighting the key role played in such a context by interaction mechanisms that take place between nano-additives and dispersing bituminous medium.

“…It was shown that the anti-aging property, rutting and fatigue cracking performance of nanosilica modified asphalt binders are enhanced and the addition of nanosilica in the control asphalt mixture significantly improves the dynamic modulus, flow number and rutting resistance of asphalt mixtures. The nanotechnology, with the usage of asphalt and asphalt mixture properties, has the following benefits [9]:  Improve the storage stability in polymer modified asphalt;  Increase the resistance to UV aging;  Reduce the moisture susceptibility under water, snow and deicers;  Improve the properties of asphalt mixtures at low temperature;  Improve the durability of asphalt pavements;  Save energy and cost;  Decrease maintenance requirements.…”

During the past years different researchers have studied the causes of failure of flexible pavements and they offered variety of alternatives for solving these failure problems such as rutting, fatigue and low temperature cracking which are sourced from moisture susceptibility and also temperature sensitivity of either asphalt, aggregate or the asphalt mixture as a whole. This study is conducted to determine the optimum amount and potential applicability of zycotherm nanomaterial in asphalt and asphalt concrete mixtures with two different systems: directly applying to bitumen and diluting and applying to aggregate in order to address the solution of potential failure problems in flexible pavements. The study is carried out experimentally by conducting tests on bitumen and bituminous mixtures. Tensile strength test and retained stability tests were performed on bituminous mixture in order to measure the tensile strength ratio (TSR) and the retained stability index (RSI), which are both the indexed parameters to determine the mixture resistance to de-bonding and disintegration in the presence of water. Penetration, softening point, RTFOT, PAV, BBR and DSR tests were also performed on bitumen to determine the effect of zycotherm on bitumen's contribution on rutting, fatigue and low temperature cracking of the mixture. It is found that using zycotherm material greatly increases the resistance of asphalt mixture to moisture induced damages and also increases its resistance to rutting, fatigue and low temperature cracking.
