The UVB-1 productivity of 2 m3 per hour
UVB-1 bitumen unit is designed for production both anionic and cationic bitumen emulsions, which are used in road construction as follows:
- base coat on old road top before application of asphalt-concrete;
- preparation of cold asphalt concrete mixes;
- surface treatment of road top;
- thin film protective coats;
- patch repair of roads etc.
The unit is designed for operation at asphalt concrete production facilities. It can be operated either outdoors under canopy or indoors.

Water pipeline is equipped with a mesh filter.
Flux pipeline is equipped with mesh filter.
Manual valves are also installed on pipelines.
The heating system is equipped with valves:
- input;
- output.
The unit is equipped with temperature and pressure sensors.
Water temperature is measured at the following points:
- water supply;
- blend supply;
- bitumen to unit supply;
- bitumen to mixer supply;
