Preparation and Properties of OMMT/ SBS Modified Bitumen
Abstract:
Organophilic montmorillonite (OMMT)/SBS modified bitumen composites were prepared by melt intercalation. The physical properties and ageing properties of OMMT/SBS modified bitumen were investigated. The results showed that OMMT/SBS modified bitumen exhibited a decreasing penetration, an increasing softening point, and a decreasing ductility. Compared with that of SBS modified bitumen, the OMMT /SBS modified bitumen can enhance the aging resistance of SBS modified bitumen.
