“…Moreover, an effect of the GO content can be qualitatively assessed, since the native membrane is very damaged, while few cracks are present on the surface of the MGLQ ( Figure 4 h,k), and even less are on the surface of the MGHQ ( Figure 4 i,l). Thus, we can state that the presence of GO in bitumen increases the oxidative thermo-stability of the bituminous membranes and also delays the degenerative phenomena generated by UV radiation [ 50 , 51 , 52 ].…”

In this work, innovative graphene oxide–doped waterproofing bituminous membranes, also called roof bituminous membranes, were prepared and characterized in terms of physicochemical and vapor transport properties. The results showed that the introduction of a small amount of GO increased the mechanical resistance of the doped membranes compared to the native one. Moreover, the addition of the GO leads to a remarkable chemical stability of the membranes when exposed to UV radiation and high temperatures. Furthermore, a decrease in water vapor permeation was observed when GO was present in the membrane matrix compared to native bituminous membranes, demonstrating that an addition of GO can boost the waterproofing properties of these bituminous membranes.

“…The first stage is the mixing, spreading and rolling processes, accompanied by transport, storage, heating and mixing of hot aggregates, which causes the effect of short-term aging. The second stage mainly refers to the service stages of pavements, which are vulnerable to the impact of natural environments and climatic changes and, therefore, produce the effect of long-term aging [33].…”

Multidimensional nanomaterials, is a resource that has been formed over time becoming a revolutionary technology with a transcendent character providing the use in asphalt construction procedures, benefiting in the aspects of resistance in the environments to the field of civil engineering, in the same way it is a way in the advance for a better conservation of horizontal works with a favorable impact on the materials used, helping to preserve the care of the environment. In such a way that, in this article, a systematic review is reflected, around the exhaustive research in the databases such as Scopus and Science Direct, compiling a sum of 85 articles, which are indexed in journals from 2017 to 2021, carried out correspondingly on the different investigations of the management of multidimensional nanomaterials in asphalts. The objective of this literary review is to transmit various research by authors such as: the impact on the life cycle of asphalt, the performance it produces, the profitability and the advantage of the teaching that multidimensional nanomaterials have left, to later show results that show a growth in yields in asphalts through the application of multidimensional nanomaterials, So that it presents greater efficiency in the resistance to aging of the asphalt it is concluded that the nanomaterials reduce the environmental impact caused by the field of the constructions, improving the anti-aging capacity of the asphalt.

“…In Wang’s paper, the high-speed shear mixing method combined with ultrasonic dispersion technology was adopted to solve the problem of the dispersion of nanomaterials in asphalt binder and the asphalt binder samples were prepared by the melt-blending method. In addition, his research also illustrated that CNTs could reduce the attenuation of physical properties and improve the aging resistance of pure asphalt binder [ 16 ]. Wang et al believed that CNTs could reduce the degradation of SBS during the aging process, and the oxygen-uptake amount of blends combined with SBS and CNTs was lower than that of neat SBS modifiers, demonstrating its important effect on the anti-ageing properties of the SBS-modified asphalt binder [ 17 ].…”

In order to explore the influence mechanism of carbon nanotubes on the ultraviolet (UV) aging properties of the SBS-modified asphalt binder, the changes of functional groups in the one-dimensional infrared spectrum and two-dimensional infrared correlation spectrum are studied in this paper. The results show that the UV aging process of the SBS-modified asphalt binder is the process of alkane chain cleavage and reorganization, the formation of oxygen-containing functional groups and decomposition of SBS. The incorporation of carbon nanotubes can reduce the mutual conversion of methyl and methylene functional groups, inhibit the decomposition of butadiene and the destruction of C = C double bonds in SBS. The degradation of SBS during the process of UV aging leads to the change of many functional groups and acceleration of the aging of the SBS-modified asphalt binder. The addition of carbon nanotubes can effectively alleviate the degradation of SBS and the formation of oxygen-containing functional groups at the early stage of UV aging, and reduce the influence of these two changes on other functional groups; thus, improving the anti-aging performance of the SBS-modified asphalt binder.
