Effect of Incorporating Ram-Fat and Oil into the Bitumen Grade 60/70

The ability of a pavement to resist fatigue cracking, rutting, and thermal cracking is mostly dependent on bitumen, which assists in minimizing the occurrence of pavement distress. The objective of the study is to determine the optimum ram fat and oil (RFO) content suitable for the application of bituminous mixtures. Saturated fats and oils consumption in excess can boost blood levels and may lead to bad low-density lipoproteins cholesterol, which raises the danger of heart failure and stroke. To minimize this problem, this study encourages the incorporation of RFO into bitumen to reduce the consumption of fats and oils in our society. The characteristics of the standard and RFO-modified binders were evaluated by penetration, softening point, and ductility tests. The RFO content (1.0%, 2.0%, 3.0%, 4.0%, and 5.0% by mass of the bitumen) was blended with the bitumen for 35 minutes with a mixing speed of 1000 rpm. The result of the optimum RFO content was discovered at 3.0% which improved the performance of the mixture. It was found that bitumen grade 60/70 documented a significant improvement with the addition of RFO content. The optimum RFO content can be raised with a smaller bitumen grade.
