Abstract: Enhancing the quality of AC 60/70 using crumb rubber and SBS polymer has its limitations. These limitations are in terms of lower than standard penetration properties, softening point and ductility based on the polymer modified asphalt cement TISI 2156-2547 standard. This research aimed at eliminating the problem by using AC 80/100 and modifying it with crumb rubber or SBS polymer at different quantities. Two types of AC were compared in this research. The qualities tested were penetration, softening point, ductility, flash point and weight loss due to heat. The results of the quality of properties tested were analyzed based on TISI 2156-2547 standardfor AC. Furthermore, the research goes on to analyze the cost effectiveness of the modification and found that modified AC 80/100 has better qualities than AC 60/70 but is 5% higher in cost. Modifying AC 80/100 with 5 wt.% crumb rubber and 4 wt.% SBS polymer will decrease the penetration and ductility problem compared to modifying AC 60/70 with the same additives. However, the softening point is still a problem for both grades of AC. © (2014) Trans Tech Publications, Switzerland.
