“…Additives of adhesive nature are most widely used in the production of asphalt concrete [3][4][5][6][7][8][9]. The introduction of such additives can improve the wetting conditions of the bitumen surface of mineral materials, forming an absorption layer, facing the polar groups to the surface of the mineral material and the hydrocarbon part in the bitumen volume.…”

The road industry is one of the important components of the economy. Quantitative and qualitative changes in the road industry require new technological approaches to road construction. The higher the transport-operational level of roads, the less the negative consequences of motorization are manifested. The condition of highways and their compliance with the international standards largely depends on the observance of construction technologies of road pavement, and the road pavement itself should have layers of strong, frost and temperature resistant monolithic materials which provide a long period of exploitation. The paper presents the peculiarities of the application of different types of modifiers for bitumen. It discusses their advantages and disadvantages, the importance of selecting the composition of the bituminous and mineral mixture. The use of crumb rubber as a modifier allows to realize the concept of a closed resource-saving technology of construction of roads. This approach will allow, on a technologically sound basis and taking into account the real needs of road construction materials, to restore the road network.

“…The quantitative relationship between the amount of added basalt fibers in asphalt binders and mixtures is not clear, but the approximate percentage range of basalt fiber to asphalt is basically consistent in asphalt binder and mixture. From the previous literature [ 15 , 16 , 25 , 34 ], the appropriate basalt fiber content should exceed 0.5%. Additionally, based on the previous research [ 15 , 35 , 36 , 37 , 38 ], the optimum asphalt content of modified SMA mixtures can reach up to approximately 6.7%.…”

This paper investigates the effects of basalt fiber content, length and asphalt-aggregate ratio on the volumetric and strength properties of styrene-butadiene-styrene (SBS)-modified asphalt mixture reinforced with eco-friendly basalt fiber. An experimental scheme was designed to optimize three preparation parameters for the Marshall test indices based on response surface methodology (RSM). The results showed that basalt fiber content presents a more significant effect on air voids, voids in mineral aggregates and voids filled with asphalt. Basalt fiber length is more related to Marshall stability, and flow value exhibits a significant variation trend with asphalt-aggregate ratio. The optimization of preparation parameters is determined as follows: basalt fiber content is 0.34%, length is 6 mm, asphalt-aggregate ratio is 6.57%, which possesses favorable and reliable accuracy compared with experimental results. Furthermore, basalt fiber reinforced asphalt binder and mixture were also studied, and it was found that basalt fiber can enhance the performance of asphalt binder and mixture in terms of cone penetration, softening point, force ductility, as well as pavement performance tests.

“…Every year the amount of plastic and polyethylene waste increases, which leads to destructive effects on flora and fauna everywhere. One of the ways to solve the mentioned problem of polymer waste recycling is their use in the modification of asphalt-concrete mixture and bitumen [3][4][5][6][7]. Thus, two problems are solved at once: reuse of plastics, polyethylene, and other polymer waste and improvement of asphalt concrete pavement with an increase in its service life.…”

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.
