Products: Road bitumen BND 130/200 buy wholesale price from the manufacturer in Russia, Bashkortostan.
BND 90/130 - oil road bitumen is used in the repair and creation of new road surfaces, as well as in asphalt plants for the production of asphalt concrete.
The main role is to bind the constituent components: crushed stone, mineral powder and sand into a single whole, while maintaining the required plasticity and strength at the same time.
Packing: a cube weighing 1000 kg.
Minimum shipment: 10 - 20 tons
Payment form: 100% payment; prepayment by agreement.
Shipment form: EXW, FCA 450076 Bashkortostan, Ufa, Chernyshevsky street, house 10a
Country of origin: Russia
Manufacturing company: Bashexport, OOO
This is especially important when installing asphalt road surfaces.
The bottom line is: road bitumen has certain characteristics that vary depending on
from the ambient temperature.
Many will probably remember the asphalt melting in hot summer, when it becomes soft like plasticine. In winter, asphalt becomes fragile, which is directly related to the negative property of road bitumen - to lose its plasticity at sub - zero temperatures.
In order to minimize seasonal damage to the road surface, asphalt concrete plants, in different climatic zones, use different types of bitumen, differing in viscosity, plasticity, softening temperature and fragility.
Oil refineries produce two main types of road bitumen - viscous and liquid.
Bitumen BND and BN are viscous.
It is the most used type in road construction.
For the possibility of laying asphalt in the cold season, so - called liquid bitumen are produced.
They are obtained in the following way: refineries add special thinners (something like solvents) to it, which, after laying (pouring), evaporate, returning it to a more viscous (original - undiluted with thinners) state.
However, it should be noted that such asphalting technology significantly degrades the environment.
And in itself, winter asphalt paving has come to naught in recent years, due to its low technology and low efficiency.
If during winter concreting there are some options for preserving the quality of the poured concrete (formwork heating, PMD additives), then with asphalting everything is somewhat more complicated.
Types and grades of bitumen recommended for use in road construction, in various climatic zones:
In the first climatic zone, with an average monthly winter temperature up to - 20 ° С:
- BND 200/300
- BND 130/200
- BND 90/130
In 2 - 3 zones, with an average monthly winter temperature of 10 . . . - 20 ° C:
- BND 200/300
- BND130 / 200
- BND90 / 130
- BND 60/90
In 2 - 4 zones at temperatures - 5 - 10 ° С:
- BN 200/300
- BN 130/200
- BN 90/130
- BND 130/200
- BND 90/130
- BND 60/90
- BND 40/60
In 4 - 5 zones, with the lowest value of the average monthly temperature not lower than + 5 ° С:
- BN 90/130
- BN 60/90
- BND 90/130
- BND 60/90
- BND 40/60
