dc.description.abstract	© 2020 American Society of Civil Engineers. This paper introduces two novel methods of using waste materials i.e., steel furnace slag (SFS), coal wash (CW), and rubber crumbs (RC) in rail tracks. One method is to optimize the mixtures of SFS, CW, and RC (SFS+CW+RC matrix) compacted with the standard compaction energy to serve as a subballast material. The other one is to examine the potential usage of CW and RC mixtures (CW+RC matrix) which are compacted under adjusted compaction effort. To investigate the geotechnical properties of these waste mixtures, comprehensive laboratory tests have been conducted. Based on the test results, the stress-strain relationship is studied with special focus on the effect of rubber content on the ductility and energy-absorbing potential of the proposed mixtures. In addition, for the CW+RC matrix, the role of rubber content and compaction effort on the compaction and degradation characteristics of the material is examined.

Abstract:

© 2020 American Society of Civil Engineers. This paper introduces two novel methods of using waste materials i.e., steel furnace slag (SFS), coal wash (CW), and rubber crumbs (RC) in rail tracks. One method is to optimize the mixtures of SFS, CW, and RC (SFS+CW+RC matrix) compacted with the standard compaction energy to serve as a subballast material. The other one is to examine the potential usage of CW and RC mixtures (CW+RC matrix) which are compacted under adjusted compaction effort. To investigate the geotechnical properties of these waste mixtures, comprehensive laboratory tests have been conducted. Based on the test results, the stress-strain relationship is studied with special focus on the effect of rubber content on the ductility and energy-absorbing potential of the proposed mixtures. In addition, for the CW+RC matrix, the role of rubber content and compaction effort on the compaction and degradation characteristics of the material is examined.
