Asphalt rheology greatly affects the performance of asphalt mixtures. One of the properties and behavior of asbuton is visco-elastic which is a rheological parameter. Asbuton's visco-elastic properties will affect the durability of the pavement layer. Therefore, knowing the rheological properties of pure asbuton, especially the proportion of visco-elastic asbuton, is expected to improve the rheological properties of oil asphalt. This study aims to evaluate the mechanistic rheology of asphalt modified Asbuton on the stiffness modulus of asphalt. The methodology used in this study is an experimental method, with asphalt mechanistic rheology testing. The results showed that the asphalt stiffness modulus (E*) increased with the addition of Asbuton content. In addition, a review of the effect of temperature with the asphalt stiffness modulus (E*) shows that the higher the test temperature, the lower the asphalt stiffness modulus (E*). Based on the minimum criterion limit of asphalt stiffness modulus, the optimum level of asbuton addition is obtained, which is 30% asbuton content into asphalt pen 80/100.
