The USB-2
asphalt emulsion plant

Bitumen emulsions produced on USB-2 asphalt emulsion plant are applied:

in road construction for tack coating of old road surface before application of asphalt;
for production of cold asphalt mix;
for surface treatment, to create thin-film protective layers;
for patch repairs;
in Multimac and Slurry Seal technologies.

Bitumen emulsion unit is designed for production of:

Cationic bitumen emulsions

Cationic emulsions - they are not sensitive to the volume of water introduced into the composition. Cationic emulsion allows to accurately predict the time of setting, which is an important factor in road works.
Anionic bitumen emulsions

Anionic emulsions - on the contrary, react to the content of water and a large number of mineral impurities in water. Anionic bitumen emulsions set with water evaporation that largely depends on weather conditions (temperature and humidity of air) which complicates their use in road construction.
Slow setting, medium setting and rapid setting emulsions, modified bitumen emulsions

Slow setting emulsions are used for tack and prime coats, as well as for emulsion-mineral mixtures.

Medium setting emulsions are used for tack and prime coats, and for seal coats, is used for cold- mix paving mixtures.

Rapid setting emulsion are used for surface treatment and surface priming through filling or spraying;

Modified bitumen emulsion is prepared on modified bitumen or with a number of modifying additives (latex, polyethylene, epoxy resin, synthetic rubber, synthetic resin, etc.).

The advantages of bitumen emulsion over hot and diluted bitumen are:

Economical. The production of bitumen emulsion uses 40-50% less energy than in heating and preparation of hot bitumen. More energy is saved during storage of bitumen emulsions. They can be stored in a liquid form for a long time without heating.
Technological. Unlike hot and liquefied bitumen, emulsified bitumen can be used with cold and wet mineral materials.
Ecological compatibility. Bitumen emulsion does not emit harmful substances into the atmosphere during its preparation or application compared to hot and liquefied bitumen. It is also fire and explosion-proof

Continuous Asphalt Modification Plant

Modified asphalt is used in:

Road construction (top layer asphalt, asphalt concrete mixes, protective layers of cement concrete coverings, surface treatment, etc.)
Hydraulic engineering (covering layers for pipes, pools, reservoirs, dams).
Roofing (waterproofing materials for roofing, crack sealant mastics).

Continuous Modified Bitumen production unit is designed for:

Modification of bitumen by adding polymers, adhesives and plasticizers, rubber polymer with resins, oils and additives

Modification with polymeric additives improves cohesive and rheological properties, deformation characteristics and strength of bitumen and asphalt concrete. Due to this, increases the coating resistance to wheel track rutting at elevated temperatures, and cracking at low temperatures and fatigue distress of asphalt concrete under the influence of loads.
Production of cutback asphalt (liquid asphalt)

Cutback asphalt is prepared by mixing asphalt cement with a petroleum solvent, while emulsified asphalt is prepared by mixing asphalt cement with emulsifiers, water, and sometimes a small amount of petroleum solvent. The aim is to decrease the viscosity and to increase the penetration of bitumen on asphalt surface. In comparison with bitumen, cutback bitumen is sprayed on different layers of roads in a notably lower temperature.

Good contact with materials.
Has good low-temperature flexibility and elasticity, and is not prone to fluidity at high temperatures.
Quickly removes stresses that arise in the layers of the road surface due to traffic.
Resistant to fatigue loads that occur during cyclic temperature changes.
Frost-resistant and with an extended temperature range.
Increased hardness and physical durability.

The use of modified bitumen instead of regular bitumen in asphalt concrete mixes allows to extend temperature range of asphalt concrete layer operability with seasonal temperature fluctuations, ensures load deformation resistance (cracking and rutting) and increases service life and road durability.
