“…% were deemed economically unfeasible. The same authors evaluated the influence of adding carbon nanofibers as mechanical reinforcement on the cost-benefit ratio of rubberized mixtures . Results showed that adding 0.5% nanofibers to asphalt modified with 15% rubber powders improved the Marshall stability by 42% and was considered the most cost-effective mixture among the mixtures with 0.5 wt.…”

Applications of end-of-life tires (ELT) for energy recovery and new products can contribute to a circular economy. This paper reviews the environmental, health, and economic aspects of various applications of ELT, focusing specifically on the use of ELT in fuel, energy, and construction. Impediments to a more widespread application of repurposed ELT include a lack of streamlined handling and recycling processes; a poor understanding of the long-term ecological, human health, and safety consequences; and very few application-specific techno-economic assessments and life-cycle analyses. The prospects for rubberized asphalt as an economical and environmentally benign application of ELT are reviewed in four areas: (1) rubber pretreatmentthe most effective techniques are chemical or microwave radiation, and the most sustainable technique is microbial devulcanization; (2) aging behaviorrubber particles delay aging in asphalt through several mechanisms; (3) techno-economic benefitsrubberized asphalt improves the cost-efficiency and energy-efficiency of asphalt; and (4) environmental emissions and leakage concernsthe risk of heavy metals and hazardous pollutants such as polycyclic aromatic hydrocarbons and volatile organic compounds contaminating the ecosystem or causing occupational diseases in workers. There are four priority directions for future research on rubberized asphalt: (1) determine the critical aging point; (2) describe the self-rejuvenating behavior; (3) quantify the long-term leachate under extensive weathering; and (4) compare the ecological aspects of pretreatment techniques in terms of potential greenhouse gas emissions and human health.

“…Many researchers have suggested the modification of asphalt mixes using additives, and a majority of those additives have produced high-quality outcomes. Hence, modifying the properties of asphalt mixture using additives is of paramount importance in achieving the goal mentioned above [11][12][13][14][15][16][17].…”

Marshall Test is one of the tests used for asphalt mixture. This test has six parameters, including stability, unit weight, flow, void in mineral aggregate, voids in total mix, and voids filled with asphalt. Further, the additional cost of various additives to the asphalt mixture for building one kilometer of the road is a negative parameter. However, using additives improves the technical characteristics of the asphalt mixture. Therefore, making a proper choice among the alternatives would be a hard task. This paper tries to provide an appropriate method for mixing the design of asphalt mixtures to select the best alternative by considering all technical criteria. For this purpose, the concordance analysis method, which is one of the compensation models of the Multi-Criteria Decision-Making (MCDM), was used. The results showed that the concordance analysis method using a pairwise comparison strategy combines the different criteria to prioritize alternatives and to propose the best alternative. Therefore, this method can be used as a superior method for mixing the design of asphalt mix compared to conventional methods.

“…Among these materials, nanomaterial have been used due to their inherent properties, especially in asphalt mixtures. Improvements in mechanical properties such as fatigue strength, rutting depth, elastic modulus, and other engineering properties are among these results (Rafi et al, 2018;Barati et al, 2020;Zahedi et al, 2017b;Zahedi and Zarei, 2016;Zahedi et al, 2017b;Zarei et al, 2020a;Zahedi et al, 2020a). Nano carbon black is one of the nanomaterial that has recently been considered in the pavement industry.…”

Nanomaterial have been considered as one of the new additives by researchers for use in asphalt pavement. In this study, economic analysis along with technical analysis of the effect of different percentages of Nano carbon black on a 1 km long road was evaluated. The results showed that the addition of Nano carbon black to the asphalt mixture in low percentages reduced the Marshall stability due to the lack of proper bonding between bitumen and Nano carbon black. By increasing the percentage of Nano carbon black in the asphalt mix, Marshall Stability increased. Also, Nano carbon black has clearly shown potential for improving the permanent deformation resistance of the modified asphalt mixture. During the Marshall Quotient test, more than two times increase in rutting resistance has been observed by adding more than 10% Nano carbon black to the asphalt mixture. On the other hand, the results of economic analysis showed that the project has become uneconomic in different percentages; however, due to the positive effect of adding Nano carbon black on the technical properties of asphalt mixtures, it is recommended that Nano carbon black be used sparingly in areas where the pavement suffers from a lack of load-bearing capacity.
