| Abstract: |
| The mechanics，morphology and rheology of modified ground rubber/SBR mixture were studied，The results showed that the modification of the ground rubber，resulted in the increase of tensile strength of ground rubber /SBR mixture and the decrease of its compression fatigue temperature rise；the influence of the ground rubber level on the apparent viscosity ηa decreased with the increase of the shear rate γw ;and the addition of the ground rubber led to the de-crease of the extrusion die swell，It could be predicted from SEM analysis to the broken cross-section of the mixture that the bonding at the interface between the ground rubber and rubber ma-trix improved. |
