Friction angle related to the soil failure
WebIt was expected that the friction angle increases with an increase in rubber content, or at least up to some percentage. The angularity of rubber contributes to increasing friction angle by interlocking with sand particles. According to Attom , the increase in the angle of internal friction is due to failure in the shearing zone. In this ...
