Scrap tire and asphalt could be used in the ballast layer to increase the life service and reduce the maintenance cost of the conventional ballast layer. The purpose of the research is to identify the characteristic of the ballast layer according to its elastic modulus, deformation, and abrasion. The method used was the compression test with four types of specimen, which were ballast without modification (sample I), ballast with graded scrap rubber (sample II), ballast with asphalt (sample III), and ballast with graded scrap rubber and asphalt (sample IV). The sample was modelled in a ballast box with the dimension of 400 x 300 x 200 mm. The percentage of graded scrap tire and asphalt was 10% and 3%, respectively. The result indicated that the addition of scrap tire could improve the deformation and elasticity material. However, it could reduce the abrasion of materials. Besides, the utilisation of binding material also could become the filler in the mixture and then increase the stiffness of the ballast mixture
