Treffer: Improving penetration and softening point of asbuton asphalt by adding of nano TiO2, nano mineral, and nano styrene-butadiene rubber (SBR) from waste tires.

The development of using nano-asphalt modified with nanomaterials has been extensively researched and has shown promising results in enhancing asphalt application performance. One approach to producing nano-asphalt is by using nanorubber as the base material. Nanorubber is a composite material consisting of nano-sized rubber particles. This material possesses superior mechanical properties, including high tensile strength, flexural strength, and good wear resistance. Additives that can be used in the production of modified asphalt include Styrene-butadiene rubber (SBR), TiO<subscript>2</subscript>, and Asbuton minerals. The results of research conducted to achieve optimal outcomes were supported by Python software using the Scikit-Learn regression method. The optimization results showed good physical properties of the asphalt, with a penetration value of 61.12 and a softening point of 65.85°C. The results of the validation test on the optimization value show an error value of <5%. [ABSTRACT FROM AUTHOR]
