USB-3 Bitumen modification unit 16 m3/hour production capacity

This is a 16 m³/hour bitumen modification¹Polymer modification of bitumen is the incorporation of polymers in bitumen by mechanical mixing or chemical reaction. unit. The growing road construction and repair market leads to growing modified bitumen demand.

The 16 m³/hour unit solves that problem. The double stream process used in this unit reduces the load on the shearing part of the mill²A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. and extends mill service life.

The compatibility of bitumen and polymers is essential to obtain a high-quality final product. The polymer can absorb oil components of the binder, preserving its structure. Due to the modification process, bitumen is turned into an elastomer³An elastomer is a polymer with viscoelasticity (i.e., both viscosity and elasticity) and very weak intermolecular forces, and generally low Young’s modulus and high failure strain compared with other materials. with improved elasticity.

Modern petrochemical industry professionals attempt to maximize the yield of light oil products and extract most of the paraffin-naphthenic fractions from bitumen⁴A bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum.. This reduces its flexibility at low temperatures and softening point at high temperatures. Most modern bitumen will lose elasticity⁵Elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. at approximately twenty degrees (20 ⁰C) and begin to soften between +45 ⁰C and 48 ⁰C. The use of non-modified bitumen in both road construction, which requires a binder with a temperature range from -40 ⁰C to +70 ⁰C, and for roofing materials⁶Roofing material is the outermost layer on the roof of a building, sometimes self-supporting, but generally supported by an underlying structure., which are often subjected to temperatures up to 90 ⁰C, is inefficient. Fortunately, there are ways to change and improve the properties of bitumen by mixing it with various additives. This is best achieved using special bitumen modification units such as the GlobeCore USB-3 bitumen modification system.

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.
