Bitumen 60/70 is a specific grade of bitumen widely used in the construction and maintenance of roads. The designation “60/70” refers to its penetration grade, which indicates the hardness and softness of the bitumen. The numbers represent the range of penetration depth (in tenths of a millimeter) at standard conditions, measured by the penetration test. For Bitumen 60/70, the penetration depth ranges from 60 to 70 tenths of a millimeter.

This grade of bitumen is favored for its optimal balance of hardness and flexibility, making it suitable for a variety of climatic conditions and traffic loads. It is commonly used in the following applications:

1. Road Construction: As a binder in asphalt concrete for constructing and resurfacing roads, highways, and runways.
2. Paving: In the creation of driveways, parking lots, and other paved surfaces.
3. Waterproofing: In roofing materials and other products requiring waterproofing properties.

Bitumen 60/70’s properties allow it to withstand high temperatures without becoming too soft and low temperatures without becoming too brittle. Its durability and versatility make it a preferred choice in the construction industry, ensuring long-lasting and resilient paved surfaces.
