This research is to study the properties of AC 60/70 asphalt cement mixed with natural and/or crumb rubbers. The AC 60/70 asphalt cement was replaced by natural rubber at 5%, crumb rubbers at 11%, and mixed with natural rubber and crumb rubbers at 8%. The suitable scale of dry crumb rubber was sizing from 0.25 mm down and the testing of penetration, loss on heating, ductility, and stripping were measured. The result finds the higher viscosity homogenized of natural rubber led from ternary mixing material, better properties than binary mixing. The ternary mixing property values are more inclined toward single mixing natural rubber to 55.32 mm, 0.081 g, 29.62 cm, and 4.68 scores of penetration, loss on heating, ductility, and stripping tests, respectively. Ternary mixing natural and crumb rubbers should be subjected to more testing at other ratios to find out its suitable proportion for better properties of asphalt mixture.
