Bitumen softeners can help lower the viscosity of an asphalt mix, improving flexibility and adhesion that can lead to the production of more durable surfaces. NuMIXER® is an all-natural blend of green, prime bio-based oils designed to enhance the bitumen properties in roofing and paving applications. It is used to enhance polymer and crumb rubber compatibility and dispersion, reduce and manage viscosity, and improve low temperature properties, leading to long-term durability and better performance. NuMIXER is an environmentally friendly product, with very low odor, no VOC and safe for workers and is compatible with a wide range of bitumens.
