Chipping pre-coated with B82 binder then flood with hot binder at appropriate temperature and gently rake the mixed material to facilitate binder penetration.

¡@
Precoat selected chippings with binder and pour into top layer. Compact with wacker. Then once compacted, screed over the surface with B82 binder.

Reopen to traffic only when cooled. Generally the cooling rate is 1 hour of cooling for every 50mm of surfacing depth, but is dependent on ambient temperature.

Zebraflex B82 Bridgejoint Compound

¡@
Zebraflex B82 bridgejoint compound is a flexible hot-poured bitumen/rubber material, for use in all types of bridgejoints and construction joints where an effective seal combined with carriageway reinstatement is required.
¡@ ¡@

It is composed of a homogenous mixture of a special high grade of synthetic rubber, chemical additives, bitumen and fillers, and has the following distinct advantages:

- Very high resistance to flow, at service temperature up to 60¢XC, therefore effectively resisting tracking.
- Withstands joint extensions without de-bonding, both a low temperatures and at ambient temperatures under wet conditions.
- Excellent pourability, without any segregation of the incorporated rubber, at temperatures well below the maximum permissible heating temperature of the bitumen/rubber mixture.
Zebraflex B82 bridgejoint compound is also resistant to dilute mineral acids and alkalis, but like most bitumen/rubber compounds softens and swells when in contact with hydrocarbon solvents, mineral or vegetable oils and fats.
