This paper presents a laboratory study on the effect of chemical warm asphaltadditive on the rutting characteristic of aged binder containing waste engine oil. The agedbinder and waste engine oil were blended with 0%, 1%, 2% and 3% of chemical warm asphaltadditive. The samples were tested for rutting characteristics (rutting resistance, G*/sin  andcreep recovery) using Dynamic Shear Rheometer (DSR). G*/sin  was tested at temperature64°C and creep recovery was tested at temperature 60°C under stress of 50 Pa. The resultsshowed that the chemical warm asphalt additive slightly decreased the rutting resistance of theaged binder containing waste engine oil sample. Meanwhile, the elasticity of asphalt binderwas improved with the addition of additive by the reduction of creep compliance. As aconclusion, results of the testing showed that chemical warm asphalt additive could be appliedwith aged binder and waste engine oil with the satisfactory performance.
