European product standards cover a large variety of road materials for different applications, to accommodate local traffic loads and climate conditions. This European standard therefore also covers a large range of bitumens to facilitate the production and application of the designed paving. The variety of production techniques and applications makes it more practical to split bitumens into 20/30, 30/45, 35/50, 40/60, 50/70, 70/100, 100/150, 160/220.  Fouman Chimie Gostar is capable of producing the following grades:
