Bitumen SC-70 is a type of slow curing cutback bitumen. Here are some key points about it:
Composition: SC-70 is made by dissolving penetration grade bitumen in a petroleum solvent, typically kerosene. This reduces the viscosity of the bitumen, making it easier to handle and apply.
Slow Curing: The “SC” stands for Slow Curing, indicating that the solvent evaporates slowly. This allows the bitumen to set and bind materials over a longer, period.
Viscosity: SC-70 has a kinematic viscosity ranging from 70 to 140 centistokes (CST) at 60°C.
Applications: It is commonly used as a prime coat on road bases before the final asphalt layer is applied. This helps to bind the granular base material to the asphalt layer. It is also used in cold-laid plant mixes, surface treatments, and for patching.
Specifications: SC-70 contains about 50% bitumen by volume and is manufactured according to ASTM D 2026M-15 standards.
