Diffusion of components of asphalt into waste rubber is of vital importance to improve the performance of rubber modified asphalt,while the related researches are scarce. Diffusion of components of asphalt into waste rubber at different temperatures has been investigated in this work. Rectangle rubber was immersed in asphalt at certain temperature for a period of time. And the mass increment of rubber was measured to determine the diffusion rate of components of asphalt into rubber. The experimental results indicated that the diffusion rate of components of asphalt into waste rubber increases along the temperature,but the diffusion rate of components of fractions oil which is distillated from catalytic cracking slurry is much higher than that of components of asphalt. Compared with asphalt,fractions oil enjoys lower viscosity and better permeability with higher content of saturates and aromatics. All the characteristics are contributed to the efficient diffusion of components of fractions into waste rubber.展开更多
