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.
