The use of recycled materials is a new tendency in the field of railway engineering. Steel slag aggregates (SSA) are one of the recycled materials derived from the steel industry. The application of SSA in ballasted railway tracks requires mechanical examination. In the present paper, the shear behavior of the ballast layer constructed by SSA...

Under the high requirement of ballast materials and the frequent maintenance of high-speed and heavy-haul railway, the maintenance cost and material consumption become an important problem. Several methods are used to increase the stability and service life of railway structure, also using recycled materials in ballast bed construction can be a...

Ballast degradation is frequently observed under cyclic loading, and results in bearing capacity and drainage problem of ballast track. To keep the stability and safety, periodical maintenances are needed, such as cleaning and replacement, which produce a huge amount of wasted ballast. Thus, reusing the deteriorated ballast can become a...

This thesis aims to analyse the conservatism in the current Dutch recommendations on the external friction angle 𝛿 of diaphragm walls: 𝛿 = 𝑚𝑖𝑛[𝜙, 20°] (for curved slip surfaces) (CUR/COB, 2010), by means of an experimental investigation. Based on literature, two sources of conservatism are identified: 1) filter cake contamination by excavated...

The present work quantified the laboratory geotechnical variability by repeatability direct shear test (DS) on alluvial fine-grained soils. The effect of laboratory variability of geotechnical parameters (cohesion c' and friction angle ϕ′) on slope stability was investigated. A mixture of compacted fine sand (40%) and clayey silt (60%) taken...
