AVIRON Crackfill

Description

 

Aviron Crackfill is a medium setting, cationic, polymer modified bitumen emulsion, with improved adhesion to mineral surfaces.

After setting a durable, highly elastic binder is formed to accommodate small cracks.

 

Uses

-   Filling of cracks and/or small joints in bituminous or cementicious constructions.

-   Filling of holes and pores in new asphalt constructions to achieve a closed smooth surface.

-   Repairing and closing hair-cracks in the surface of worn out concrete and asphalt pavements.

Pre-treatment 

 

The cracks and surfaces to be treated must be clean and free from oil, grease and dust.

Application     

Aviron Crackfill can be applied cold directly from the drum, using a watering can, squeegee, or filling tray when only the cracks are treated.

When the whole surface has to be treated, to improve the surface texture (more thickness), the Aviron Crackfill can be applied by using long-

haired  brushes or rollers or can  be sprayed with a special  spraying equipment.

During application enough emulsion to penetrate the cracks completely must be used (pre-filling may be necessary).

Directly after treatment the Aviron Crackfill must be covered fully with aggregate 1-3 mm or sand, depending on the surface structure.

Almost immediately after covering (approx. 15 minutes with drying weather conditions) the treated areas can be trafficked.

-   General precautions

-   Pails and drums must be stirred or rolled before use.

-   Protect the material from frost or direct sunshine.

-   Do not carry out work during wet or frosty weather.

-   Protect Aviron Crackfill from drying out on brushes or in the equipment.

-   When using spraying equipment the emulsion must be strained directly
before spraying.

-   Prewet brushes and rollers with water.
