“…The decrease in S composition compared to AC 60/70 is due to damage during the mixing process. The same thing is related to the higher dominant C element increasing the strength and hardness values of asphalt as stated by authors [37][38][39], and S which is sensitive to temperature by researchers [40].…”

Many road pavements have experienced a decline in quality, giving rise to the issue of nanotechnology materials in the construction sector which is expected to overcome this problem. Indonesia, which is the largest palm oil-producing country in the world, needs to utilize its waste, including for pavement materials. The research aims to examine adhesion, and characteristics of asphalt and mastics asphalt based on physical properties, SEM (Scanning Electron Microscope) and contact angles. Palm oil waste was processed into medium-Nano carbon material, then mixed with asphalt cement 60/70 at a temperature of 150ºC and stirred using a high-speed drill for 45 minutes until evenly mixed. The research results show that the carbon Nano material used has an average surface area of 115 nm2 which produces dominant elements of C atoms and S atoms. The low penetration value, high softening point and ductility prove that the ability to increase the strength, temperature resistance and cohesion of mastics asphalt is better than AC 60/70. Apart from that, the medium level of waste used can increase the adhesion of mastics asphalt. This can be seen from the contact angle obtained which is 125.830º which is smaller than using 60/70 asphalt which is 129.258º.

Unlike the conducted studies in the field of reinforcing the asphaltic mixture, this research has used the multi-criteria decision-making method to determine the optimal percentage of the asphalt mix, which was reinforced with rubber powder and carbon fibers. After adding different percentages of two kinds of additives, i.e. rubber powder and carbon fibers conjointly, conducting Marshall Tests, analyzing the data and plotting the needed diagrams, it was observed that adding these two additives leads to a change in the results of Marshall Tests. Analyzing the diagrams, the optimal percentages for combining the rubber powder with carbon fibers were obtained, 15% and 0.5%, respectively having the best effect on the asphalt mix. Subsequently, the extra cost caused by adding the additives to the asphalt was evaluated by conducting an economic analysis. Then, six Mar-shall Parameters were used as six indices in the concordance analysis method, which is a multi-criterion decision-making method. Ultimately, the superior alternatives were proposed according to the results of the ranking. Ac-cording to the results, the suggested alternatives differed from the estimated alternative and the concordance analysis method proposed better alternatives.

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.
