Crumb Rubber, obtained through retreading of used rubber tires, has the opportunity to be used in asphalt mixtures, thereby reducing the waste of used tire rubber. The purpose of this study was to analyze and compare the effect of adding Crumb Rubber with large particle sizes, which is passing sieve Number 4 and being retained by sieve Number 8, and small particle sizes, which is passing sieve Number 16, in the Asphalt Concrete-Binder Course mixture. The effect of Crumb Rubber is measured using the Marshall and Indirect Tensile Strength parameters. The proportion of addition of Crumb Rubber is 0% and 1.5% of the total weight of the aggregate. The binder used in this study was Penetration Grade Asphalt of 60/70, produced by Shell. This study shows that the addition of Crumb Rubber increases the values of Void in Mineral Aggregate, Void in Mix, and Marshall Flow, but decreases the values of density, Void Filled with Asphalt, Marshall Stability, Marshall Quotient, and Retained Marshall Stability, as well as decreases the values of Indirect Tensile Strength. Crumb Rubber with small particle size turned out to have a better effect than Crumb Rubber with large particle size.
