RISInvestigation of the Performance of Steel Slag–Granite Ballast Mixture under Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: In the current study, we explored the performance of steel slag ballast (SSB), granite ballast (GB), and a slag–granite ballast mixture under cyclic loading conditions using a large-scale track simulation apparatus. In ...
Influence of Coal Fouling on the Shear Behavior of Elastan-Treated Railroad Ballast
Publisher: ASCE
Abstract: The shear behavior of coal-fouled unstabilized ballast and that stabilized with Elastan was assessed in direct shear mode at various normal stresses (σn) and shearing rates (Sr). The materials used in the test were fresh ...
Performance of Geogrid-Reinforced Rubber-Coated Ballast and Natural Ballast Mix under Direct Shear Conditions
Publisher: ASCE
Abstract: Rubber-coated ballast (RCB) is a new innovative ballast aggregate obtained by coating natural aggregates with recycled crumb rubber by using polyurethane binder. The objective of RCB is to reduce the ballast degradation, ...
Effect of Polyurethane Content on the Performance of Ballasts under Static and Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: The effect of polyurethane content on the behavior of ballast was assessed based on large-scale direct shear and cyclic loading tests. The large-scale direct shear tests were performed at normal stresses (σn) of 40 to ...
Experimental Investigation of Coal-Fouled Steel Slag Ballast–Granite Ballast Mixtures under Static and Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: The performance of coal-fouled steel slag ballast (SSB), granite ballast (GB), and 60%SSB+40%GB (SSB60) mixture were assessed using direct shear and cyclic testing apparatus. Additionally, chemical composition, mineralogical ...
