Chemical modification of waste cooking oil to improve the physical and rheological properties of asphalt binder

The performance of asphalt binder modified with waste cooking oil (WCO) is affected by the quality of the WCO itself because of the degradation process during frying activity. The quality of WCO can be determined by conducting an acid value test, wherein an increased acid value has caused the decrea...
