Iranian Bitumen (60/70 & 80/100 Grade) – Complete High-Quality Industrial Description

Iranian Bitumen, especially 60/70 and 80/100 penetration grades, is one of the most widely used and globally acclaimed bituminous binders for road construction, asphaltic mixes, waterproofing systems, and various industrial applications. Iran has long been recognized worldwide for producing bitumen of the highest consistency, purity, and performance. Its stable viscosity, strong adhesive properties, excellent weather resistance, and long-lasting durability have made Iranian Bitumen a preferred international standard for infrastructure and industrial projects.

Produced primarily from vacuum bottom (VB) through advanced refining processes, Iranian Bitumen offers high purity, uniform grade accuracy, and exceptional stability. Its controlled penetration value, strict quality testing, and superior packaging standards have positioned it among the most trusted bitumen materials for large-scale construction across many countries.

Product Characteristics

1. Penetration Value

Grade 60/70 – Ideal for moderate to heavy traffic roads in warmer climates.

Grade 80/100 – Preferred for colder climates or roads with lighter traffic.

These penetration ranges ensure balanced flexibility, strength, and optimal bonding between bitumen and aggregates, making pavements resistant to cracking, rutting, and deformation.

2. Strong Adhesion & Cohesion

Iranian Bitumen forms a powerful bond with aggregates, creating a dense and durable asphalt mixture. This strong adhesion results in:

Higher pavement life

Reduced rutting

Increased load-bearing capacity

Smoother road surfaces over long periods

3. Excellent Weather Resistance

Iranian Bitumen performs exceptionally well under varied climatic conditions:

High temperature: Does not soften excessively, preventing rutting.

Cold climate: Maintains flexibility, preventing cracks.

Rain & humidity: Provides outstanding waterproofing protection.

4. Stable Viscosity

The refined viscosity of Iranian Bitumen ensures easy mixing and coating of aggregates, resulting in:

Faster production

Lower energy consumption

More uniform asphalt mixes
