Comparison of Shear Strength Characteristics of Unsaturated Soil From Triaxial Compression Tests with Direct Shear Tests

Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

Effects of Ballast Degradation on Shear Strength Behavior from Large-scale Triaxial Tests

Ballast, typically comprising large sized aggregate particles with uniform gradation, is an essential layer in the railroad track substructure. Functions of ballast include facilitating load distribution and drainage, maintaining track geometry and track stability, and providing track resilience and noise absorption. Throughout its service life, ballast goes through changes in gradation and par...

evaluation of mechanical behaviour of sandstone and andesibasalt rockfill materials using triaxial & direct shear tests

the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...

Permeability and Direct Shear Tests Characteristics of Railway Subballast

Permeability, filtration and shearing strength were widely considered to be the key properties in evaluating the performance of railway subballast. An investigation on these key properties of railway subballast was presented in this paper. A constant head permeability test and a middle scale direct shear test of railway subballast were conducted in the research, aiming to investigate the subbal...
