Bitumen softeners are designed to lower bitumen stiffness to allow for greater flexibility and cracking resistance. This can help stabilize mixes with varying bitumen quality and maintain the integrity of the roadway or roofing surface. ReNUBIT® is a proprietary petroleum-based bitumen softener designed to improve polymer compatibility, solvency, and stability. It is effective with a wide range of bitumen found around the world in the paving and roofing industries. ReNUBIT produces softer grades of bitumen that support high polymer and/or crumb rubber levels while improving low temperature properties, fracture toughness, and fatigue resistance.
Using Oils to Rectify Bitumen Quality Variabilities
Crude oil is sourced from locations around the globe. Fuel refineries then further alter bitumen characteristics. Crude slate blending, and bitumen blending, add another layer of variability to the nature of the product. All of these factors result in a collective issue of “quality” in bitumen, resulting in a commodity that varies widely in composition and properties. Because of [...]
