The ballast layer is a common conventional structure of the railway track used in Indonesia, due to it is easy to maintenance, to build and low costs of maintenance compared to slab track. In this study it is used four types of specimen, which were using crumb scrap tire and bitumen materials. The percentage of crumb scrap tire and bitumen was 10% and 3%. The method used for experiment was the compression test to evaluate the deformation, abration and elastic modulus. The result indicated that ballast with crumb scrap tire has lowest stiffness compared to the three other samples. The crumb scrap tire increases deformation up to 9,12 mm with stress was found to be 77,72 kPa. However it decreases the abration of materials into 0,6% and elastic modulus of 81,6% from reply without mixture. Ballast without modification produces a deformation 5.72 mm with stress of 196,59 kPa and elastic modulus of 9907,64 kPa
