*SAMIseal PBD
Polymer modified bitumen
SAMIseal PBD is a polymer modified bitumen used as the binder in spray sealing applications where a High Stress Seal (HSS) or Strain Alleviating Membrane (SAM) is required. SAMIseal PBD is manufactured by blending Class 170 bitumen with polybutadiene polymer, specifically for but not exclusively, to meet the Queensland Department of Main Roads specification for S0.3B sealing binder. SAMIseal PBD also meets the AustRoads and NSW Roads and Traffic Authority's S35E sealing binder specification.
Features
SAMIseal PBD is a binder which exhibits superior aggregate retention and is tough, with elastomeric properties.
- Greater toughness
- High softening point
- Superior aggregate retention
- Crack retardation
- Compatibility with a broad range of bitumens
- Early sweeping capability
- Sprayed at a lower temperature than crumb rubber and SBS binders
- No transportation limitations
Applications
- Used for most sprayseal applications including a SAM where minor cracking is to be covered.
- For quick aggregate adhesion
- Situations where minimal loose aggregate is paramount
- High stress sites
- Intersections
