A significant disadvantage of shortening life of the roadway is the aging of the binder. The main factors that lead to the deterioration of the properties of oxidized oil bitumen are described in the article.It is found that considerable loss of binding properties happens even before the commissioning of the road. An artificial aging of the bitumen samples according to GOST 18180 was performed and the indexes before and after the process of 5 and 10 hours aging were compared.
