| Abstract: | The FCC slurry is used to pretreat crumbled rubber to improve compatibility of bitumen and crumbled rubber and produce crumbled-rubber modified bitumen with good hot storage stability. The process conditions are investigated and performances of modified bitumen are analyzed by various testing means. The results show that the pretreated-crumbled-rubber modified bitumen is better than crumbled-rubber modified bitumen in respect of hot storage stability, low-temperature ductility, cracking resistance, elasticity restoration and viscoelasticity etc. |
