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. ReNUBITยฎ 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 supportโฏhigh polymer and/or crumb rubber levels while improvingโฏlow temperature properties, fracture toughness, and fatigueโฏresistance.
The Role of Asphalt Additives in Roadway Paving
Asphalt continues as a cornerstone of road construction globally, with 90% of roads paved globally using asphalt. As infrastructure demands accelerate, environmental standards are also on the rise. However, traditional asphalt comprised of only bitumen and aggregate often falls short of modern expectations for performance, durability, and sustainability.ย ย ย Asphalt additives are purpose-designed materials that can elevate pavement [...]
