“…The flexible and rigid pavements are the two most important roads or highways. Over 95% of the roads in the world are flexible asphalt pavements [1,2] because of its good driving comfort [1,3,4], durability [5,6,7,8], and resistance to water damage [9,10,11]. The main material component of asphalt pavement structure is asphalt mixture [12,13].…”

Although the rutting resistance, fatigue cracking, and the resistance to water and frost are important for the asphalt pavement, the strength of asphalt mixture is also an important factor for the asphalt mixture design. The strength of asphalt mixture is directly associated with the overall performance of asphalt mixture. As a top layer material of asphalt pavement, the strength of asphalt mixture plays an indispensable role in the top structural bearing layer. In the present design system, the strength of asphalt pavement is usually achieved via the laboratory tests. The stress states are usually different for the different laboratory approaches. Even at the same stress level, the laboratory strengths of asphalt mixture obtained are significantly different, which leads to misunderstanding of the asphalt mixtures used in asphalt pavement structure design. The arbitrariness of strength determinations affects the effectiveness of the asphalt pavement structure design in civil engineering. Therefore, in order to overcome the design deviation caused by the randomness of the laboratory strength of asphalt mixtures, in this study, the direct tension, indirect tension, and unconfined compression tests were implemented on the specimens under different loading rates. The strength model of asphalt mixture under different loading modes was established. The relationship between the strength ratio and loading rate of direct tension, indirect tension, and unconfined compression tests was adopted separately. Then, one unified strength model of asphalt mixture with different loading modes was established. The preliminary results show that the proposed unified strength model could be applied to improve the accurate degree of laboratory strength. The effectiveness of laboratory-based asphalt pavement structure design can therefore be promoted.

“…The uses of hydrated nano-lime can reduce by 75% in order to increase the resistance capabilities of the asphalt mix to moisture attack. The incorporations of 2-4% of multidimensional nanomaterial (in asphalt binder masses) significantly increase the rutting resistance capabilities in asphalt mixture [71].…”

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.

“…[28], For example, the formation of grooves in the asphalt surface usually occurs due to exposure to high temperatures, which soften the asphalt binder, therefore the properties of this material play a fundamental role in the final performance of the pavement layer. [29,30] while cracking usually occurs due to a hardening of the asphalt binder due to low temperatures [31], therefore the performance and duration of the asphalt layer depends a lot on the development and / or behavior of the binder in the face of traffic loads and climatic changes; Based on these problems, different techniques or methods have been proposed to modify the asphalt binder in order to counteract the aforementioned problems, among them the use of polymers and nanomaterials stand out [32].…”

Currently, one of the methods to improve the properties of materials in construction is the use of nanomaterials. The objective of this paper is to review the technological advances in the application of nanomaterials, which improve mechanical properties when used in concrete, soils, pavements, among others. A total of 86 articles corresponding to the Scopus, Ebsco, Science Direc and IOP Science databases were reviewed. The studies show that with the application of nanomaterials, positive results are obtained in the improvement of the compressive and flexural strength of concrete, improvement in the stabilization of soils and in asphalt, avoiding the formation of grooves and cracks. The studies conclude that the applicability of nanomaterials in the construction industry is a good alternative from a sustainable point of view, in order to reduce the indiscriminate use of non-renewable resources
