Provides binder stabilization and crack control in SMA, OGFC, and waterproofing products.
FBR500 cellulose fiber additive in bituminous mixtures:
- Binder stabilization: The porous structure of the fibers absorbs excess bitumen and locks it within the mixture. Minimizes drain-down (bitumen drainage) risk in SMA and OGFC mixtures.
- Rheological modification: Increases mixture viscosity, ensuring ease of compaction and stability during paving.
- Mechanical strength: Enhances resistance to rutting (wheel track deformation) and thermal cracking.
- Waterproofing systems: Provides crack control and flexibility in roofing membranes and bituminous waterproofing products.
