“…Both IDT and Marshall stability tested under wet conditions of HMA with SFCC are higher than that of the compared mixtures. However, the TSR and MSR of the HMA mixtures in Figure 13 are equivalent, and the values are higher than the required value of 80% [34,35].…”

The spent fluid catalytic cracking (SFCC), waste from the petroleum industry, is nonstop increasing and causing environmental pollution in Vietnam. This study is an attempt to recycle SFCC in pavement construction. The study investigated the effect of SFCC, as a filler material in the hot-mix asphalt (HMA), on the essential characteristics of the asphalt concrete mix. First, the optimum percentages of bitumen and SFCC rate were investigated based on the Marshall design method. The HMA with SFCC showed more enhanced stability, flow, and other Marshall properties than the asphalt concrete mixture with the optimum limestone filler of 5%. Besides, the effects of SFCC rates on Marshall characteristics were explored. Second, performance tests were conducted to compare the mix with the different optimum content fillers of SFCC, limestone, and Portland cement. The tests include wheel tracking, indirect tensile, fatigue, and dynamic modulus tests to evaluate the performance of HMA with SFCC. It was found that the asphalt mixture with the optimum SFCC filler content can enhance pavement performance and improve the rutting and cracking resistance of the asphalt pavement.

“…Nanosilica materials are not only abundantly available but also have a large surface area that facilitates high adsorption, high dispersion ability, and high purity [78]. Due to these factors, they are commonly used to improve the moisture susceptibility of asphalt mixes [79,80]. Nanosilica is a very stable material with low toxicity.…”

Despite the numerous benefits for preserving the hydrological cycle, permeable pavement systems (PPSs) found their major application in parking spots and for light traffic scenarios due to their limited durability and strength. To make the PPSs suitable for heavy traffic conditions without significant distresses, research is shifting toward the adoption of novel binders and additives for designing multifunctional porous asphalt mixtures which make up the surface course of PPSs. Certain additives are well known for enhancing the durability of dense graded asphalt mixtures and improving fatigue and rutting resistance. However, the studies on the influence of additives on abrasion resistance and binder draindown, which are the common problems in porous asphalt mixtures (PAMs), are still not well established. This paper summarizes best practices performed on PAMs and recommends possible future research directions for its improvement. Particular emphasis is placed on strength and resilience of PAMs by incorporating additives like nanosilica, crumb rubber, warm-mix additives, fibers (such as cellulose, glass, steel, and synthetic fibers), and some eco-friendly materials. It was found that different additives seem to have different effects on the properties of PAMs. Moreover, the combination of additives has synergistic benefits for the performance of PAMs, especially in urban pavements.

“…The Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) specifies that multidimensional nanomaterials are materials with an external dimension, as well as internal structuring having one or more types of dimensions in the range up to 100 nm, presenting several characteristics that are innovative in comparisons of the same materials without characters at certain nanoscales [12]. Being efficient having a significant effect on improving the properties of permanent deformations in bitumen and mixtures [13].…”

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.
