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.
Bitumen Softeners for Asphalt: Frequently Asked Questions
Bitumen softeners are an important tool in the asphalt industry for maintaining and improving roadway performance. The key advantage of adding softeners to bitumen is their ability to improve low-temperature performance. This results in enhancing penetration, reducing stiffness, and lowering the binder’s PG grade to minimize cracking. By restoring workability, bitumen softeners can help maintain the binder’s balance between [...]
