Bitumen is a material widely used in construction, characterized by excellent hydrophobic and adhesive properties. It is mainly used for asphalting highways. This material is also very often used as a waterproofing agent in the construction of buildings and structures. In this article we will understand in detail what bitumen is, what its properties are and its scope of application.

Definition

Bitumen is a dense, viscous, black, resin-like substance. It is usually supplied in pieces, which are melted before use. The composition of bitumen is very complex. It is a combination of a hydrocarbon base with its derivatives, as well as metals, oxygen and nitrogen. Various heteroorganic compounds are also present in this material. In general, the composition of bitumen is so rich that identification of all its components is simply impossible.

How it is produced

The main product used to prepare bitumen is oil. There are only three main types of this material:

Concentrating oil residues by vacuum distillation. Final product It is soft and fusible. Using this method, bitumen is obtained from highly resinous (sulphurous) oil.
Oxidation of tar (oil residue) by blowing it with oxygen at a temperature of +180...+300 degrees. This method produces a heat-stable elastic material.
Mixing of residual and oxidized petroleum products with distillates.

Natural bitumen

Most often, this material is produced artificially using the three technologies described above. However, there is also natural bitumen, the characteristics and uses of which are approximately the same as regular bitumen. It occurs in nature and forms unique lenses. Natural bitumen is practically never found in its pure form. Most often it impregnates some sedimentary layer. Typically these are rocks such as sandstone or limestone. In this case, pure natural bitumen is obtained by first grinding stones. Sometimes such asphalt rock is simply thoroughly ground and used in road construction.

Types of bitumen by area of use

According to the area of application, this material is divided into four large groups:

Construction bitumen. Used for foundations, submerged wooden structures, etc.
Roofing. It is used to protect roofs of residential, industrial and public buildings from moisture.
Petroleum road bitumen. The most common option used for preparing asphalts.
Insulating. Used to protect metal pipelines from moisture and corrosion.

Road bitumen

This hydrophobic material is most often used in the construction of highways. There are two main types of road bitumen:

Viscous. Obtained from petroleum.
Liquid. This variety is made from viscous bitumen. Petroleum products are used as a diluent.

Viscous petroleum road bitumen is used in the construction of highways in the warm season. Liquid material is used in cold weather. Viscous bitumen is heated to its melting point before laying. Liquid material can be used either cold or heated. Some time after laying, due to oxidative processes, such bitumen thickens and forms a dense, moisture-proof elastic film.

What characteristics should you pay attention to when purchasing?

There are only three main parameters by which the quality of bitumen can be determined:

softening temperature indicator;
ductility (degree of ductility of the bitumen thread);
penetration (viscosity).

The latter indicator is determined by immersing a needle or cone in bitumen at a certain temperature.

Marking

It is very easy to find out which bitumen is intended for which type of work. To do this, you need to look at the markings.

Construction bitumen is marked with the letters BN.
Road - BN or BND.
Roofing - BNK.

After the letters in the marking there are two numbers separated by a forward slash. The first number indicates the softening point, the second - the degree of viscosity. The latter is determined by immersing a needle in bitumen at a temperature of 25 o C.

Brands of viscous road bitumen

As already mentioned, such material is supplied in pieces or in barrels. When paving, BN (petroleum bitumen) and BND (petroleum road bitumen) are used. According to GOST, only ten types of this material are produced (BDN from 200/300 to 40/60, BN from 200/300 to 60/90).

Liquid road bitumen

This material is marked separately. There are only two varieties of it:

SG - thickening at medium speed.
MG - thickening slowly. This variety is used in road construction in climatic zones II-V.

In this case, after the letters there are also two numbers separated by a slash, indicating the permissible range of ductility (at a temperature of 60 o C with a 5 mm hole on the viscometer).

When purchasing a batch, you need to check the certificate (passport) for liquid petroleum road bitumen. The SG brand, just like MG, BDN and BN, must comply with GOST+. We’ll talk about what this document is a little lower.

Safety precautions when working with bitumen

You should be quite careful when using this material. Bitumen is flammable. The fire hazard of a particular brand is determined by the following indicator: It is higher for viscous construction, road, roofing and insulating bitumens, and lower for liquid bitumens. Therefore, when working with the latter you should be especially careful.

Among other things, when performing operations related to the application, storage, transportation, etc. of bitumen according to the rules industrial safety you are required to wear protective clothing. This protects the worker from hot, difficult-to-wash drops coming into contact with the skin.

Bitumen quality certificate

Bitumen sold by enterprises must comply with GOST 2245-90 standards. However, today many companies produce products of this type with improved characteristics. Therefore, bitumens of one or another new brand are accompanied by special certificates certified by the heads of laboratories, also called passports. They indicate parameters such as penetration, ductility, softening point of the product, etc.

Such a document is issued not only for viscous, but also for petroleum road liquid MG bitumen. The quality certificate is a guarantee that the characteristics of the material comply with those declared by the manufacturer. On the document in mandatory the company seal is affixed.

Of course, there must be a passport for liquid petroleum road bitumen SG, as well as for roofing and insulating bitumen. New brands of this material include, for example, BND-U and Euro BV. In relation to them, quality standards are determined not by GOST, but by TU and STO. When producing Euro BV, the requirements of the European standard EN 12591 are also taken into account.

Most common brands

In construction, petroleum road bitumen 90/10 is most often used. Manufacturers produce and sell it in huge quantities. It is used to waterproof foundations, underground parts of wooden supporting structures, interpanel seams, basements and walls. It differs from another fairly popular brand, BN 70/30, by more heat melting. This expands the scope of its use, since the film produced by it is able to withstand high heating temperatures.

In the construction of highways, petroleum road bitumen MG130/200 is often used. It is usually used in those regions where the air temperature in winter does not fall below 20 o C. This material forms a reliable and very smooth road surface.
