The UVB-20 productivity of 20 m3 per hour

The UVB-20 bitumen emulsion unit is designed for production of either anionic or cationic bitumen emulsions used in road construction for the following purposes:

  • preparation coating for old road top before application of asphalt concrete;
  • preparation of cold asphalt concrete mix;
  • road top surface treatment;
  • thin protective coat preparation;
  • patch repairs of roads etc.

The unit will benefit asphalt concrete production facilities.

The unit may be operated either indoors or outdoors under canopy.

Ambient temperature range for operation is from +5oС to +400С.
