Evonik is providing a broad range of technologies to serve the road construction industry. VESTENAMER® and TEGO® Addibit products provide solutions for today‘s requirements such as durability, reduction of emissions and energy consumption, and thus support sustainable road construction and maintenance.
Rubber modified bitumen/asphalt
The use of ground-tire-rubber (GTR) in asphalt significantly enhances performance and durability of road surfaces. Processing of rubber-modified bitumen and asphalt is often challenging. VESTENAMER® as an additive overcomes such challenges fundamentally, leading to much easier processing and even better performance. Using the VESTENAMER®-effect, an ecologically and economically reasonable resource like GTR, can be turned into a top performing road construction material.
