BituPlus Bitumen SC70 is a slow-curing (SC) cut-back asphalt, comprising penetration grade asphalt cement and a slow-volatility diluent or cutter. Our Cutback Bitumen SC-70 adheres to the specifications for slow-curing cutback petroleum asphalts, as outlined in ASTM D2028-97 (reapproved in 2004). This product is designed for use in the construction and treatment of pavements.
SC-70 and SC-250 grade cutback asphalts exhibit similarities to residual refinery products, often utilized as heavy fuel oils like bunker C or Number six fuel oils. These SC cutback materials, whether in their straight run form or blended with a relatively non-volatile substance like gas oil, are also referred to as “road oils.”
Key Properties of BituPlus Bitumen Cutback SC70, classified according to ASTM/EN15322:2009 standards, include:
- Slow Curing: SC70 is categorized as a slow-curing cutback bitumen, suitable for specific construction and pavement applications.
- Quality Assurance: BituPlus ensures the quality of Cutback SC70 by collaborating with international inspectors. Each shipment undergoes rigorous quality and quantity checks during the loading process onto vessels. Additionally, our dedicated QC team conducts batch test reports to verify product quality before shipping.
Applications:
BituPlus Bitumen Cutback SC70 is ideal for use in the construction and treatment of pavements, following the specifications of ASTM D2028-97 (reapproved in 2004).
