Economical and Technical Study on the Effect of Carbon Fiber with High Strength on Hot Mix Asphalt (HMA)

Abstract

In this article by adding different percentages of carbon fiber with high strength and doing the necessary Marshall tests, it was observed that the Marshall Resistance and its Flow increased. Due to their armed properties, the carbon fibers have a positive effect on Marshall Resistance. According to the results, in-creasing the percentage of fibers, reduces the resistance, so that the resistance of the sample containing 1.5% of carbon fiber is almost 32% more than the resistance of the sample without fiber. According to the results, the increased resistance compared to the previous researches and other fibers stems from the kind of fiber used in it and its high resistance. After increasing the fiber percentage to 3, a 12% decrease in the resistance was seen. On the other hand, by changing the percentage of the fibers added to the aggregates, the Flow will change, so that the sample containing 3% of fiber is almost 189% more Flow than the base sample. The economic analysis was used for a three-lane road. The results showed that economically speaking, due to their high price, these types of fibers are recommended to be used in restricted and optimal areas.

Surface Wrinkling for Flexible and Stretchable Sensors

“…The rapid developments in flexible electronics have induced new challenges and requirements for fabricating highperformance sensors for various analytical and biomedical applications. [19,20,200,201,247] Despite significant progress in the production of novel micro and nanostructured sensors, the trade-offs between different characteristics have hampered the fabrication of efficient sensors that require simultaneous and parallel properties. Therefore, various strategies, including surface wrinkling and additional surface structures, have been introduced and developed to enhance the sensors' physical and chemical characteristics (Tables 1-3).…”

Application of Multi-Criteria Decision-Making in Achieving the Right Mix Asphalt Mixtures

“…The cost criteria were calculated as the additional cost of adding additives to the mixture for each kilometer of a highway [1,2] and [14,15]. The following table shows raw Pij data (results of Marshall) used in the Concordance analysis [37][38][39].…”

“…In the design of asphalt mixtures, the aim is to determine the best mixture in terms of technical and functional characteristics [1][2][3][4][5][6][7][8][9][10]. Many researchers have suggested the modification of asphalt mixes using additives, and a majority of those additives have produced high-quality outcomes.…”

“…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].…”

Laboratory study on the properties of concrete pavement containing blast furnace slag and Gilsonite

“…A proper design of pavements' type can reduce the costs of the road (Zarei and Zahedi, 2016;Miryalad and Nokken, 2015;Zahedi and Zarei, 2016;Rahman et al, 2014;Zarei et al, 2020a;Zarei et al, 2021;Zarei et al, 2022a;Zarei et al, 2022b;Zarei et al, 2022c) and improve technical performances Zarei et al, 2019;Rezaei et al, 2020;Barati et al, 2020;Zahedi et al, 2020;Rassafi et al, 2021;Zarei et al, 2020b;Xiong et al, 2023;Tabasi et al, 2023a;Tabasi et al, 2023b;Fatemi et al, 2023). The main purpose of using pavement is to provide safety, convenience, and traffic control (Huang, 2004).…”
