Properties and use of liquid bitumen

Features bitumen

There are several types of bitumen, which we detail below.

Natural bitumen

Natural bitumen - a byproduct material in the processing of petroleum products, as well as various rocks.The main feature - it's resistance to acids, alkalis and water.

Building bitumen Building bitumen

- product of oil refining and mixing with a variety of building components such as:

• rubble
• processed products masloproizvodstva

This species differs from the other resistance to getting wet, resistance to high temperatures and fire.The main brands of construction bitumen: BNK:

• 90/40
• 45/180
• 90/30
• 45/90

Road bitumen

This type is the most popular among the rest.When using it, you need to take into account penetration, as it is necessary to use a bitumen with high penetration, to warm, on the contrary, the low for the colder areas.For the laying of roads mainly used by such brands as the bitumen:
BND

• 90/130
• 40/60
• 60/90
• 200/300

number of brands of bitumen each day increases.This is due to the fact that manufacturers are constantly adding various ingredients, thereby increasing certain characteristics, increasing:

• elasticity
• temperature data on fragility
• temperature data for rasparki
• pentratsii factor

Almost all of the additional chemicalscomponents should increase these properties.Price matches the quality of the bitumen and the direction of application of the material.These characteristics are indicated on the label.

Application bitumen

Natural bitumen

Natural bitumen is hardly ever used in the construction industry.Natural bitumen with non-oxidized components, often used for paving roads in Europe, as well as some states of America.This kind of natural bitumen is produced only in the presence of a new generation of equipment, to the west there is a lot of factories and plants.

Road bitumen

The name of this bitumen says what it is used.This type of well can withstand heavy loads and is used for pavement laying.Basically, it is used in the production of asphalt.It plays a role, he connects the component.Thanks to him, small stones and sand, as well as additional components of asphalt together into a dense solid mass.

Depending on the density of bitumen is partitioned into two types:

• Viscous Liquid

Viscous used in the construction and laying of roads, and the liquid for road repairs and the roof of the roof.Bitumen must comply with EU standards as well as the use of the best materials increases the durability of buildings and roads, but also prevents a variety of defects.If you want to get a good high quality bitumen then you need to apply to the plant where it is produced.

Building bitumen

used in the construction of the foundation and the work to repair the roof and pavement.Mostly used the liquid form of bitumen.This type of bitumen requires special trucks for transport, it is called - bitumen.Working with him is quite difficult because he quickly grasped, and you need to act quickly.Typically, it is used for finishing the joints in the roofing construction, as well as building putty joints.With this type of bitumen to achieve the best possible sealing.
