Description of stress testing of railroad bed materials in Great Britain; tested soils included clay and marl; stresses were determined between ties and ballast and under rails; pressure cells were used for quasi-static and for dynamic testing; smaller sized pressure cells of series Y and Z are most suitable; test and theoretical values show close agreement; Mohr's circle representation demonstrates that vertical and horizontal stresses are principal ones; results obtained have enabled realistic stress levels to be adopted in laboratory tests of repeated stressing of soils.
