| 摘 要： | Bitumen was modified with desulfurized crumb rubber (DCR) in the present of reactive additives . The effect of the kinds and content of the reactive additive on properties of DCR modified bitumen (DCRMB)was investigated. The morphology of DCRMB was characterized by SEM and the changes of the chemical structure of DCRMB without and with the addition of the reactive additive were analyzed by FTIR. The experimented results show that the softening point, the elasticity recoveray and the storage stability of DCRMB were improved significantly by the addition of the reactive additive. This is because that a network structure of rubber in DCRMB was formed and the chemical reaction between C = C double bonds in bitumen and DCR has happened after the reactive additive was added into DCRMB.
