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.

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 [...]

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 [...]

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. Asphalt additives are purpose-designed materials that can elevate pavement [...]
