Introduction to Cutback Bitumen SC-70

Cutback bitumen SC70 is a key component in various construction applications, known for its ability to maintain liquidity at ambient temperatures. This article explores the properties, uses, manufacturing process, safety guidelines, and FAQs related to SC-70 cutback bitumen

 Properties of Cutback Bitumen SC-70

Cutback bitumen SC70 typically contains between 12 and 40 percent distillate, impacting its viscosity and application characteristics. Understanding these properties is crucial for effective utilization in construction projects, especially in road surfacing and waterproofing.

Manufacturing Process of SC-70 Asphalt

It is produced by fluxing asphalt cement with a less volatile distillate, such as gas oil. This process results in materials similar to heavy fuel oils, making SC-70 suitable for various applications, including prime coats and cold-applied treatments.

Uses of Cutback SC-70 Asphalt

IT finds widespread use in penetrating prime coats, patching mixtures, and waterproofing applications. Its easy application and adhesion properties make it ideal for bonding loose mineral particles and sealing surfaces.

Packing and Safety Measures

Packing of SC-70 cutback bitumen typically involves thick steel drums on pallets to prevent leaks during transportation and storage. Safety precautions include referring to Safety Data Sheets (SDS), eliminating ignition sources, wearing appropriate personal protective equipment (PPE), and avoiding product contact with skin or water systems.
