Abstract
To date, the issue of polymer waste recycling becomes relevant, because every year the amount of plastic and polyethylene waste increases, which leads to devastating effects on flora and fauna everywhere. One of the ways to solve this problem of polymer waste recycling is to use them to modify asphalt-concrete mixture and bitumen. Thus, two problems are solved at once: reuse of plastic, polyethylene, and other polymer wastes and improvement of asphalt concrete pavement with an increase in its service life. The paper presents a discussion of the use of modified bitumen in the construction of highways and roads, the design and technological solutions, features of the technology of modified bitumen, as well as the results of laboratory tests of modified bitumen, based on which was decided on the advisability of using. The use of the combined approach of the road pavement allows increasing the service life of the road.
