Bitumen penetration grade 60/70

Understanding Bitumen penetration grade 60/70

Bitumen penetration grade 60/70 indicates a penetration value ranging from 60 to 70 under standard test conditions, making it a popular choice for paving applications. This type of bitumen is essential for producing hot mix asphalt used in road construction and repair. Supplied by Shiv Shakti Tar & Chem products, it is manufactured through aeration on vacuum bottom in specialized bitumen production units. With its penetration grade falling between 60 to 70, this bitumen undergoes rigorous testing, including penetration and softening point tests, to ensure quality and consistency. Its thermoplastic nature allows it to soften at higher temperatures and harden at lower temperatures, making it versatile for various climates. Bitumen penetration grade 60/70, known for its semi-hard properties, is widely utilized in road construction projects and the manufacturing of asphalt pavements. Its performance parameters, such as adhesion, rheology, and durability, are influenced by its unique temperature-viscosity relationship. The penetration test, measuring the depth to which a standard needle penetrates vertically into a sample of bitumen at 25 degrees Celsius, determines its hardness and suitability for different applications.
