Asphalt

Bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product. Before the 20th century, the term asphaltum was also used the word is derived from the Ancient Greek. The Company Bitumen Material Plant (BMP) sold over 745 thousand tonnes of Bitumen in Kazakhstan, CIS, and overseas for the year 2018. we also reached a new level in terms of the production of the modified binder.

The primary use – (70%) of asphalt is in road construction, where it’s used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including the production of roofing felt and for sealing flat roofs.

Naturally occurring asphalt is sometimes specified by the term “crude bitumen”. Its viscosity is similar to that of cold molasses, while the material obtained from the fractional distillation of crude oil boiling at 525 °C (977 °F) is sometimes referred to as “refined bitumen”.

Road Bitumen

Road oil bitumen is obtained by the oxidation of products of the direct distillation of oil and selective separation of oil products (de-asphalting asphalts, selective refining extracts). Another technology for producing bitumen is compounding (mixing).

Area of application: binder for the construction and repair of road and airfield coatings.

The company completed the program for setting up the production of bitumen according to the requirements of the new interstate standard GOST 33133-2014 of the technical regulation of the Customs Union.

The new standard implies the expansion of methods for assessing the quality characteristics that finished products should have. In accordance with the document, not only standard parameters are regulated, such as conditional viscosity indicators and resistance to high-temperature influences, but also the bitumen resistance to aging during its transportation and in the preparation of asphalt mix.
