Grade 60 / 70

60/70 Penetration Grade Bitumen

60/70 penetration grade bitumen is a type of bitumen with a penetration value of 60 to 70 at 25°C. This penetration grade, which is considered semi-hard, makes 60/70 bitumen a heavy-duty material suitable for road construction and repair. It is commonly used in asphalt production.

Key properties of 60/70 bitumen:

• High viscosity: 60/70 bitumen has a high viscosity, which makes it resistant to rutting and shoving at high temperatures.
• Good adhesion: 60/70 bitumen has good adhesion to aggregates, which ensures a strong bond between the asphalt and the road surface.
• Excellent durability: 60/70 bitumen is highly durable and can withstand heavy traffic loads.
• Suitable for a wide range of climates: 60/70 bitumen can be used in a wide range of climates, from hot to cold.

Applications of 60/70 bitumen:

• Road construction: 60/70 bitumen is the most commonly used bitumen for road construction. It is used in the production of asphalt pavements for both new and existing roads.
• Repair and maintenance: 60/70 bitumen can also be used to repair and maintain existing roads. It can be used to fill potholes, cracks, and other imperfections in the road surface.
• Other applications: 60/70 bitumen can also be used in other applications, such as waterproofing, roofing, and pipe coating.

Storage and handling:

60/70 bitumen should be stored in a heated tank at a temperature between 120°C and 160°C. It should be applied at a temperature between 160°C and 180°C.

Safety precautions:

• 60/70 bitumen is a hot material and can cause burns.
• It is flammable and should be kept away from open flames.
• Adequate ventilation should be provided when working with bitumen.
