N2 - Particle breakage is a basic characteristic of granular soils, which plays an important role in the micro- and macro-mechanical properties of sand. However the breakage behaviour of sand mixed with rubber is currently not well understood. In the present study, a series of tests up to high stress levels was conducted on Completely Decomposed Granite (CDG) soil and granular tyre rubber mixtures to investigate the particle breakage behaviour. The CDG soil was chosen as the host sand due to its fragile particles which easily break during loading. Two different sizes of CDG sand particles and granular rubber particles from waste tyres were used in the tests, with different ratios of sand to rubber content. The breakage behaviour trends were similar for the different particle sizes, but with different relative breakage values. While breakage increased with stress level, the breakage reduced when the percentage of granular rubber increased, and at a critical percentage of the granular rubber, the breakage reached a minimum. © 2015 Taylor & Francis Group.
