BlackRock Bitumen: Penetration Grade Bitumen 35/50
Bitumen 35/50 is a hard penetration class bitumen mainly used to manufacture high-quality road surfaces. It has an input value from 23 to 30 (1/10 mm), making it one of the most challenging characters in the EN 12591 standard. Due to its high viscosity and excellent resistance to deformation, this character is particularly suitable for areas with warm climates and subject to roads subject to heavy traffic. The Bitumen 35/50 works exceptionally well under high pressure and temperature, ensuring long-term lasting durability and reducing maintenance costs.

Bitumen35/50 contributes to better-aging properties, and thermal stability contributes to its popularity in significant infrastructure projects, such as highways, highways, industrial areas, and runways at airports. The ability to withstand thermal cracks and routing creates two materials for engineers and designers targeting reliability and performance.
The designation “35/50” refers to the penetration grade of the bitumen, indicating its hardness. This grade signifies that under specific test conditions, a standard needle will penetrate the bitumen to a depth of between 3.5 and 5.0 millimeters. This characteristic makes our 35/50 bitumen particularly suitable for:
