The flash point of roofing bitumen (BBR) is not less than +240 °C. The possibility of self-ignition is allowed at a value not lower than +300 °C. To produce this material, the distillation products of (straight) oil are oxidized and mixed with asphalt and extracts from the oil industry. The resulting composition is used for the manufacture of:
- hydroglass isol,
- bitumen paper,
- parchment,
- roofing material,
- mastics, etc.
BNK bitumen grades:
- BNK 90/30 - used for applying the cover layer;
- BNK 40/180 - used for impregnation;
- BNK 45/190 - necessary for the preparation of the coating composition and impregnation.
The main physical and structural quality of BNK bitumen is absolute water tightness. The presented materials prevent moisture from entering the treated substrates, repelling it, and protect the surface from damage of various kinds. Moderately plastic composition of roofing bitumen is also characterized by increased heat resistance. It is excellent for operation in difficult climatic conditions.

There are differences in the areas of application of roofing bitumen:
- BNK-40/180– roofing bitumen used for impregnation;
- BNK-45/190- roofing bitumen, used for impregnation and formation of the cover layer;
- BNK-90/30- roofing bitumen, used only for the cover layer.
The production of high-class construction bitumen is influenced by the components that make up the oil and the sequence of the production process.
Technical requirements
To comply with the regulations in the production of bitumen, it is necessary to comply with standard technical requirements:
Rationing for the BNK-40/180 brand:
Rationing for the BNK-45/190 brand:
- softening temperature - 40 - 50 ° С.
- needle penetration depth at 25°C - 160 -220 mm.
- discrepancy after heating the mass - 0.80%.
- flash point - 240°C.
- mass fraction of water - traces.
- mass fraction of paraffin - 5.0%
Rationing for the BNK-90/30 brand:
- softening temperature - 70 - 95 ° С.
- needle penetration depth at 25°C - 25 - 35 mm.
- brittleness temperature – -10°C.
- solubility with organic solvents - 99.5%.
- discrepancy after heating the mass - 0.50%.
- flash point - 240°C.
Test Methods
The generally accepted test methods for oil roofing bitumen include the following physical and chemical indicators:
- penetration;
- softening;
- fragility;
- discrepancy after heating the mass;
- penetration from the original;
- flash point;
- paraffin content.
Sampling from each batch of bitumen in the amount of 0.5 kilograms is carried out according to.
Acceptance rules
After the whole party roofing oil bitumen will be prepared for shipment, a quality certificate is issued for it. Only one quality certificate is issued for each batch. A batch can be recognized as a different amount of bitumen, homogeneous in terms of quality.
Getting unsatisfactory results testing on one or more indicators leads to repeated tests, but the sample volume must be doubled. The conclusion of repeated test results is valid for the entire batch.
The manufacturer is checking for the presence of water (mass fraction) at least once every six months. Once every three months, the solubility and the proportion of paraffin (mass) are determined.
Packaging, labelling, transport and storage
Basic packaging methods apply such as clovertainers, euro barrels (metal), big bags and craft bags. Bitumen carriers are used to transport bitumen in a state ready for use.
- clovertainer has the shape of a cube. The pallet and cover are made of plywood, the walls are made of corrugated cardboard. Unpacking takes a couple of minutes with a grinder.
- metal euro barrel easy to use because the lid has a metal clamp. There is no need to unpack, just open the barrel, heat the bitumen, pour the right amount and close it again. Safety of quality is provided at the expense of a cover with a collar.
- big run- the packaging is a universal polypropylene bag, which can take the form of the container, which is designed for unloading by loading mechanisms.
- kraft bags- the most impractical container, both during transportation and when opening the package.
- bitumen carrier– tank truck with double walls and wall heating. Due to heating, bitumen does not need long-term heating at facilities under construction.
To determine whether, what type of material, its characteristics, characteristic features of storage and transportation, volume or mass, batch number and certification (if any) there is a marking, information that is applied to each commodity unit.
For oil roofing bitumen - this is BNC, numbers 40/180; 45/190; 90/30 in the numerator is the temperature at which the bitumen becomes soft, and in the denominator is the expected temperature of the solid state.
Ensuring the safety of bitumen oil in containers is produced using racks or pallets. When stored in stacks in closed warehouses, under sheds or on planned industrial sites with concrete or asphalt pavements, which ensures their protection from exposure to sunlight and precipitation.
In cases of bitumen transportation in the solid state, transportation is carried out on specially equipped collapsible forms. Transportation of products from hydrocarbons requires the provision of all necessary fire safety requirements due to self-ignition. Compliance with elementary safety rules eliminates the possibility of accidents and emergencies.
Manufacturer's Warranty
The plant for the produced oil roofing bitumen in the product passport indicates, in accordance with GOST, the material produced, the shelf life and use of no more than one year from the date of production. You can buy construction bitumen for a price of 50 rubles per 1 kg.
Safety requirements
Viscous bitumens differ: BND (oil road bitumen) and BN (oil bitumen).
Viscous oil road bitumens are produced in five grades: BND 40/60, BND 60/90, BND 90/130, BND 130/200, BND 130/200; oil (BN) - four grades: BN 60/90, BN 90/130, BN 130/200, BN 200/300.
The letters BND mean "oil road bitumen", the numbers are fractions 40/60, 60/90, etc. indicate the permissible limits for the grade of penetration depth of a standard needle at 25 ° C, indirectly characterizing the viscosity of bitumen. BND grade bitumens have good adhesion to stone materials and have a sufficiently high plasticity at low temperatures, and are resistant to climatic influences. Specifications for viscous oil bitumen are standardized by GOST 22245-90.
Viscous petroleum road bitumen is used for preparation of hot, warm and cold asphalt mixes, for surface treatment, impregnation, and also for liquefaction in order to obtain liquid bitumens used for the preparation of cold asphalt concrete, surface treatment and for mixing on the road, etc.
The properties of road bitumen are determined by the peculiarities of its composition and structure. The main indicators of this material are viscosity, ductility and heat resistance. These indicators are interrelated. With an increase in oil content, an increase in temperature and duration of exposure to loads, viscosity decreases and plasticity increases. Resins determine the astringent properties of bitumen and tar, give them plasticity, and increase the adhesive ability. Asphaltenes in bitumen and free carbon in tar increase the softening point and hardness.
Viscous bitumen is classified into one grade or another based on three main indicators: needle penetration depth, softening temperature and extensibility. Needle penetration depth and extensibility are normalized at two temperatures: 25 °C and 0 °C.
