USB-3 Bitumen modification laboratory system

The USB-3 bitumen modification laboratory system is designed for preparation of small samples (no more than 10 liters per batch) of modified bitumen¹Modified bitumen is characterized by improved flexibility and longer service life, it also has a lower brittleness temperature and higher softening temperature..

The system uses continuous bitumen²A bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. mixing process with further dispersion³A dispersion is a system in which distributed particles of one material are dispersed in a continuous phase of another material. of bitumen and polymer in the mill⁴A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting.. Unit design allows for addition of other liquid components in the process of bitumen modification.

The unit can be used by petrochemical facilities for optimization of modified bitumen production process, determining the required amount of modifying additives and using the prepared bitumen as a laboratory sample.

This product is designed for testing of known formulas of emulsions, primers and liquid rubber. It can also be used for the development of new materials and emulsifiers and the corresponding research and experiments.

Bituminous grouts — field of application

1. Bituminous grouts are classified both by fields of application and by methods of use (cold and hot coating).
2. Some grouts require preliminary surface preparation with primers. A primer is a bituminous priming material containing a bitumen and a solvent and having a high penetrability and a short drying time.
3. Types of grouts and their uses:

а) Coating grout (cold application):

• waterproofing of surfaces;
• treatment of joints and cracks;
• puttying of surfaces;
• attaching of rolled bitumen materials;
• anticorrosive protection of metal structures.

1. b) Coating grout (cold application). It can be used at sub-zero ambient temperatures. It is used for repair and forms an ultrastrong waterproof coating on the steel, concrete, and wood structures sunk deeper into the ground.

с) Bituminous-rubber grout (cold application) is used for waterproofing of foundations, walls, tanks, pipelines, etc.

1. d) Adhesive grout (cold application). Designed for attaching the extruded polystyrene to bituminous, bituminous-polymer insulating materials in foundation insulation systems.

Modified bitumen — Fields of application

1. Road construction:

• production of asphalt concrete which is used for new construction and repair of first-class roads, bridges, overpasses, road junctions, etc.;
• production of stone matrix asphalt concrete (SMA) for pavement topping of first-class highways and roads;
• production of porous asphalt concrete;
• plaсing of crack-stopping membrane interlayers.

2. Hydraulic engineering facilities:

• production of PMB-based grouts for coating of water storage facilities, swimming pools, water supply pipe linings.

3. Roofing:

• production of PMB-based rolled roofing materials (Ruberoid, Euroruberoid).

4. Bitumen shingles:

• production of grouts for laying and repair of roofing surfaces.
