Technical Advantages

Rubber modified bitumen/asphalt

The use of ground tire rubber (GTR) enhances the durability and performance of asphalt concrete pavements significantly. Processing is often challenging. A small addition of VESTENAMER® pellets dramatically overcomes the challenges, leading to an easier process mix. The improved handling and durability of asphalt rubber results in a reduction of maintenance costs.
