At Coolak, we believe that successful transactions are built on trust, transparency, and informed decision-making. This belief is reflected in several principles that guide our work: Transparency throughout the commercial process Careful verification before presenting opportunities Risk reduction before problems arise Practical and executable transaction structures Long-term business relationships rather than short-term gains These principles are not marketing statements. They are the standards by which we evaluate our own decisions.

Road & Industrial Bitumen Grades

Iranian Bitumen for Road and Industrial Applications

This category presents bitumen families for road construction, waterproofing and industrial use. As the portfolio develops, penetration, viscosity, oxidized, emulsion and other verified products can be organised here. Current supply details are available on the Iranian bitumen product page.

Comparison of Common Bitumen Families

Family

Basis of classification

Typical applications

Important parameters

Penetration grade

Penetration range such as 60/70 or 80/100

Asphalt and pavement production

Penetration, softening point, ductility and loss on heating

Viscosity grade

Classification by viscosity

Mix design and road projects

Viscosity, flash point and governing standard

Oxidized bitumen

Air-blowing process and higher softening point

Waterproofing and industrial uses

Softening point and penetration for the application

Bitumen emulsion

Bitumen dispersed in water with an encoder

Surface treatment and selected cold applications

Emulsion type, breaking time and bitumen residue

Standard, Testing and Packing

The grade must be matched to the contract standard and cargo test results. Generic wording such as “export bitumen” does not replace penetration, softening point, viscosity and other acceptance limits. Packing may include bulk, drums or big bags, but suitability depends on the grade, handling temperature and logistics route.

Bitumen forms part of the petroleum products category. For an accurate review, provide the grade or standard, application, quantity, packing, destination and Incoterm through the Coolak sourcing form.
