This research utilizes scrap rubber from motorcycle tires as a ballast layer mixture component. A compression test method was used with three test samples: ballast (sample I), ballast with 10% uniform graded scrap rubber (sample II) and ballast with 10% continuous graded scrap rubber (sample III). This research aims to analyze the elastic modulus, durability and vertical deformation of the ballast layer. It can be concluded that the elastic modulus of sample I, II, and III was 14.28 MPa, 8.53 MPa, and 3.10 MPa, respectively. Moreover, the abrasion of sample I, II, and III was 162.1 gr (3.24%), 54.2 gr (1.08%), and 50.1 gr (1%). Furthermore, at the same number of vertical deformation (5 mm), the sample I was able to receive the most considerable load that is 1980.9 Kg, followed by sample II by 1252.2 Kg and sample III by 443.7 Kg.
