The growing demands in the field of road constuction lead into the need of better results concerning both the safety and duration. One other necessity is for the maintenance time to get shorter and the road coating to get better mechanical properties in comparison with the old fashion methods. The addision into bitumen mixtures (small quantities of suitable polymers), as the international practice shows, seems to be the most efficient way to modify relogical behavior of the bitumen in order to cover the new growing technological demands. NETOIL SA pioneers in this field too, offers the ability of production of modified bitumen having the suitable, for this reason, equipment. The modified bitumens can be used in all sections of road constuction from airport to civic roads as well as in the bitumen powders for special uses (antislippings, drainers).
