EXPERIMENTAL STUDY ON COMPRESSIBILITY CHARACTERISTIC OF RUBBER-SANDS MIXTURES

Waste rubber chips bring a lot of pressure to the environment. Some researches have been done for improving the properties of soil with rubber particles in engineering. Several specimens of rubber-sands mixtures with different sands percentage composition were made and consolidation tests were done to explore the compression properties of mixtures influenced by rubber particles. The tests results were that the density curves and the stress-strain curves of the specimens with different sands fraction were presented. It was found that the density of specimens increases with the sands fraction increases approximately linearly. The specimens with a lower sands fraction are more compressible and show a larger residual deformation. The Es of specimens develops with the sands fraction increases and it grows much faster when the sands fraction is higher than 60%.
