One of the efforts to reduce road damage due to excessive loads is to increase the quality of the asphalt mixture by improving or increasing the quality of asphalt (bitumen). The use of Asbuton or crumb rubber as an additive in the pavement mixture will have a different effect on the properties of the mixture itself. The purpose of this study was to determine the comparison of the criteria for damage to Asbuton modified asphalt and asphalt modified SIR 20 crumb rubber against fatigue crack resistance and permanent deformation based on the mechanical rheological properties of asphalt and to determine the optimum levels of Asbuton and the optimum levels of crumb rubber SIR 20 that meet the specifications. The research method was carried out by examining the mechanistic rheological properties of asphalt with a Dynamic Shear Rheometer (DSR). The results of this study indicate that Asbuton modified asphalt is more resistant to permanent deformation than rubber modified asphalt while rubber modified asphalt is more resistant to fatigue cracking than Asbuton modified asphalt.
