The UVB -1 productivity of 1 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.
UVB-1 bitumen unit is semi-automatic, consists of several individual assemblies on a single frame and interconnected by pipelines.
An external source of 6 – 8 bar compressed air is required for operation of pneumatic systems of the unit.

- bitumen pump assembly pos.3;
- mill pos.4;
- water pump pos.5;
- flux pump pos.7;
- hydrodynamic mixer pos.8;
- water phase mixer pos.10 ;
- control panel pos.12;
- measuring vessel assembly: pos. 13.1 – acid; pos. 13.2 – emulsifier; pos. 13.3 – adhesion additive;
- regulation valves: pos.14.2 – blend; pos.14.3 – flux;
- flow meters: pos.15.2 – blend; pos.15.3 – flux;
- pneumatic bitumen valve pos.16;
- heated bitumen pipeline system, pos.17;
- heating oil pipeline system pos.18;
The unit if also equipped with temperature and pressure sensors. Pressure and temperature are measured in the following points:
- water/blend supply;
- bitumen supply;
- bitumen to mixer supply;
- emulsion output.
Pressure is measured in the following points:
- before the unit;
- after bitumen pump;
- before the mill.
The unit is equipped with an emulsifier tank heater:
The heater is a welded flat platform. A 200 liter emulsifier barrel is placed on the platform. A heating agent circulates through pipes in the platform.
The control panel is an air-tight metal case containing «Schneider zelio» controller, multifunction measuring regulators TC4 and TK4, protection and start equipment.
