Bituminous Products’ Information

  • Production of cold asphalt

    Production of cold asphalt

    The design and operation of cold asphalt plants are categorized as continuous type and batch type.

  • Components of Bitumen Emulsions

    Components of Bitumen Emulsions

    Bitumen emulsions are heterogeneous mixtures that often consist of two immiscible liquid phases, bitumen and water, and are stabilized with an emulsifier.

  • The uses of bitumen

    The uses of bitumen

    The most amount of bitumen, which is used in the construction industry and road construction, is also used in road and roof pavement.

  • European CE Standard for Bitumen

    European CE Standard for Bitumen

    First let’s look at the etymology and origin of “CE” to be more familiar with its meaning. CE is in fact abbreviated form of French phrase “Conformité Européne” or “Conformity European”.

  • Bitumen Density

    Bitumen Density

    The ratio of the weight of a substance to its volume is called its specific weight. However, density is the ratio of the mass of a substance to its volume. Density is independent of the gravity acceleration, nevertheless, the specific weight is affected by the gravity acceleration of the earth.

  • Penetration of Bitumen

    Penetration of Bitumen

    One of the most significant features of asphalt cement is temperature susceptibility that is obtained and evaluated in terms of penetration index (PI). Penetration and softening point tests are used to determine the penetration of asphalts.

  • Natural asphalt

    Natural asphalt

    Natural asphalt is gradually produced and obtained in natural conditions and free space caused by evaporation and transformation of existed crude oil in the nature by passage of long time (million years).

  • What is hot asphalt?

    What is hot asphalt?

    Hot-mix asphalt is a combination of hot tar and graded fine aggregates and filler which is produced and mixed in asphalt factory in a pre-defined specific situation and heat and is carried, distributed, profiled and crushed on surfaces of base and sub-base or layers of concrete.

  • Viscosity Grade (VG) bitumens

    Viscosity Grade (VG) bitumens

    Bitumens are divided into different categories based on the production method, compounds, and physical properties, such as penetration bitumen and PG and viscosity (VB) bitumens. In this section, we will review the Viscosity Grade Bitumens.

  • Bitumen tests

    Bitumen tests

    Some tests are carried out on the bitumen samples among which the following tests could be mentioned:

  • What is Hot Asphalt Recycling?

    What is Hot Asphalt Recycling?

    Hot asphalt recycling implies a set of operations during which the worn-out pavement is first removed from the road surface,
