Abstract: This paper presents the potential of scrap tire in controlling the onset of instability of sand in the constant shear drained (CSD) stress path. A series of triaxial tests in the constant shear drained stress path was ...

Abstract: In this paper, the discrete element method (DEM) is coupled with the Lattice Boltzmann method (LBM) to model the cone penetration test (CPT) of a saturated granular media. The coupled numerical model was calibrated using ...

Abstract: Slag, a by-product of the iron and steelmaking industry, has been identified as an alternative construction material; however, there are currently limited engineering reuse applications for some slags. Steel slag coarse ...

Abstract: The practical application of waste materials such as steel furnace slag (SFS) and coal wash (CW) is becoming more prevalent in many geotechnical projects. While adding rubber crumbs (RCs) from recycled tires into mixtures ...

Abstract: A number of constitutive models exist to model behavior of granular material under cyclic loading. Most of these models are useful to model soil behavior where the number of cycles is very small. Therefore, a semiempirical ...

Abstract: This paper presents the results of the influence of frequency on the permanent deformation and degradation behavior of ballast during cyclic loading. The behavior of ballast under numerous cycles was investigated through ...

Abstract: Coarse granular materials such as railway ballast and rockfill are often subjected to three-dimensional (3D) stress conditions including the influence of intermediate principal stress. Modeling the deformation and breakage ...

Abstract: This paper presents results obtained from the discrete-element method (DEM) to study the effects of particle shape on the shear behavior and breakage of ballast aggregates. In this study, a series of direct shear tests ...
