NuMIXER Archives

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.

How Asphalt Softeners Improve Workability, Compaction, and Mix Uniformity

Asphalt producers and paving contractors face constant pressure to deliver mixes that are easy to handle, consistent during placement, and durable once in service. Achieving these outcomes often depends on how well the asphalt binder flows and coats aggregate. One category of additives helping producers meet these goals is asphalt softeners, also referred to as bitumen softeners. These materials help manage binder viscosity and improve [...]

Asphalt Rejuvenators vs. Bitumen Softeners: Choosing the Right Additive

Asphalt performance is no longer defined solely by virgin materials. With increasing use of recycled asphalt pavement (RAP), tighter specifications, and sustainability targets shaping modern mix design, selecting the right asphalt additive has become a critical decision point. Among the most commonly discussed options are asphalt rejuvenators and bitumen softeners, two additive categories that are often confused but serve very different purposes. Choosing [...]

All About Crumb Rubber for Asphalt Mix Design

Asphalt technology is constantly evolving, and one of the most sustainable and performance-enhancing innovations has been the introduction of crumb rubber into mix designs. Derived from recycled tires, crumb rubber can be integrated into asphalt mixtures to improve durability, flexibility, and resistance to high temperatures. With proper mix design and additive support, crumb rubber asphalt (CRA) extends roadway lifespans while promoting environmental sustainability by [...]

Managing Viscosity in Asphalt Mixes for Improved Workability

Achieving the right asphalt workability is crucial for ensuring smooth, long-lasting roads. One of the key factors influencing workability is the viscosity in asphalt, which is a measure of its resistance to flow. Properly managing asphalt viscosity ensures mixes can be placed and compacted efficiently while minimizing aging defects such as cracking, rutting, or other deformations. Understanding [...]
