Throughout the world, both local and national authorities know that it is good business to use modified asphalt in new road projects. It is cost-efficient both medium- and long-term, because roads are less exposed to rutting and cracking. This reduces maintenance, which is not only a financial problem, but also a traffic-related problem, as roads must be partly closed during maintenance work.
The most common way to modify bitumen in modern road construction is to use the synthetic rubber SBS (styrene-butadiene-styrene). SBS is made from scarce virgin resources and is thus not only costly from an economical point of view – but also environmentally. However, SBS as a bitumen modifier may be substituted by recycled rubber powder (GENAN FINE POWDER, 0.2-0.8 mm); and this has now become standard technology with years of practical experience throughout the world.
