Bitumen emulsion plant UVB-1

(Production capacity 1 m3/hour)

The UVB-1- bitumen unit is designed for the production of anionic

and cationic bitumen emulsions, which are used in road construction for the

following purposes:

- tack-coating of the old road pavement base before laying new asphalt

concrete;

- preparation of cold asphalt concrete mixes;

- surface treatment of pavements;

- thin protective coatings;

- road top patching;

- dampproofing of buildings and structures;

- soft roofs construction and repairing.

The unit can be used on factories producing asphalt concrete mixes.

The unit is designed for operation both indoors and outdoors, for outdoors

operation use sheltered area.
