Effect of Chemical Warm Asphalt Additive on the Rutting Characteristic of Aged Binder Containing Waste Engine Oil

摘要

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 δ and creep recovery) using Dynamic Shear Rheometer (DSR). G~*/sin δ 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.
