Bitumen is an important material in the road construction industry. There are various types of bitumen, which affect its properties and uses. One type is penetration bitumen, which is obtained from the distillation of crude oil. Modified bitumen is mixed with additional materials, such as polymers or rubber, to improve its quality. Buton bitumen comes from Buton Island in Indonesia. Pure Buton bitumen is produced by extracting Buton bitumen with a purity level of almost 100%. This study examined the viscosity, shear resistance, and stiffness characteristics of bitumen from different types of bitumen. The samples of bitumen used were Pen 60/70, solid natural rubber bitumen, polymer-modified bitumen, and pure Buton bitumen. The computer program BANDS 2.0, which operates through Windows, was used to predict the stiffness properties of the bitumen. Brookfield kinematic viscosity and shear resistance tests revealed that Pen 60/70 bitumen has a kinematic viscosity of 438 centistokes (cSt) and a shear resistance of 2.89 pascals (Pa); Pure Buton Bitumen has a kinematic viscosity of 1,180 cSt and a shear resistance of 7.91 Pa; Solid Natural Rubber Bitumen has a kinematic viscosity of 889 cSt; and Polymer Modified Bitumen has a kinematic viscosity of 839.cSt, and a shear resistance of 5.87 Pa; and polymer-modified bitumen has a kinematic viscosity of 839.4 cSt and a shear resistance of 5.53 Pa. The results of the tests and analysis show a linear relationship between viscosity and shear resistance, with higher viscosity values producing higher shear resistance. Meanwhile, the penetration and stiffness of the bitumen show an inverse relationship in bitumen, with high bitumen stiffness values corresponding to low penetration values.
