What is Road+ ?

Road+ is an elastomer bitumen and asphalt modifier and is produced according to a process patented by Evonik. Ingredients are high quality rubber powder produced by Genan which is mixed by 4.5% Vestenamer®, a semicrystalline polyoctenamer produced by Evonik.

Laboratory tests and field road projects show that as a rule of thumb a standard bitumen modified with 10% Road+ as a minimum performs on level with a similar 4% SBS modified bitumen. For several of the properties, e.g. the ability to prevent rutting and the forced ductility, Road+ performs significantly better. Test reports covering the comparison of properties between Road+ and SBS modified bitumen can be downloaded from the download centre to the right.

It is of paramount importance for the product performance that the rubber powder being used is uniform in size and clean. As the world’s largest manufacturer of rubber powder from scrap tyres, Genan has the technology to live up to these requirements. The Genan rubber powder is not only clean but also consistent in size.
