Roads, like a spider web, intertwine our world up and down, and every day people build hundreds of kilometers of roadway, sometimes without even thinking about the environmental friendliness of road construction methods. The urgency of the problem of dirty road construction should not raise questions in our time, and especially in the Russian state. The article highlights the issue of reducing the risks of environmental pollution during the construction of the road network, the issue of green building is touched upon. Focal points are highlighted, which are worth paying attention to during the preparation of documentation to reduce the risks of environmental pollution. As a result, conclusions were drawn on the list of materials that should be used in order to reduce the impact on the environment.

“…Durability is the ability to resist deformation in the long-term service of asphalt life. Of interest, these studies [11][12][13][14][15][16] reported that adding plastic polymers could notably improve rutting resistance [15,16]. Studies also confirmed that adding plastic enhanced the workability and stability of the mixture [13,14,16].…”

“…Other studies [14][15][16] have displayed positive results using plastic in asphalt modification; nevertheless, few argue the use of a significant amount of plastics, such as PET and highdensity polyethylene (HDPE), for improving the mechanical properties and durability of modified asphalt. Durability is the ability to resist deformation in the long-term service of asphalt life.…”

Commercial polymers have been used in pavement modification for decades; however, a major drawback of these polymers is their high cost. Waste plastic polymers could be used as a sustainable and cost-effective additive for improving asphalt properties, attaining combined environmental–economic benefits. Since 2019, in Australia, trial segments of roads have been built using waste materials, including plastic, requiring that laboratory evaluations first be carried out. This study aims to examine and evaluate the effect of using a domestic waste plastic, polyethylene terephthalate (PET), in modifying C320 bitumen. The assessment of several contents of PET-modified bitumen is carried out in two phases: modified bitumen binders and modified asphalt mixtures. Dynamic shear rheometer (DSR) and rolling thin film oven tests (RTFOT) were utilised to investigate the engineering properties and visco-elastic behaviour of plastic-modified bitumen binders. For evaluating the engineering properties of the plastic-modified asphalt mixtures, the Marshall stability, Marshall flow, Marshall quotient and rutting tests were conducted. The results demonstrated that 6–8% is the ideal percentage of waste plastic proposed to amend and enhance the stiffness and elasticity behaviour of asphalt binders. Furthermore, the 8% waste PET-modified asphalt mixture showed the most improvement in stability and rutting resistance, as indicated by increased Marshal stability, increased Marshall quotient and decreased rut depth. Future fatigue and modulus stiffness tests on waste plastic-modified asphalt mixtures are suggested to further investigate the mechanical properties.

The paper considers the road transportation sector in the context of the negative impacts of the global economic and financial crises on the environment. The ecology-oriented development of the road construction, road repair and maintenance are described herein. The promising research and innovation development in Siberia includes the ways to increase the stability of asphalt concrete pavements, studying the possibilities of waste utilization produced by the local industrial enterprises (for example, stillage residues of the chemical industry) for the road asphalt modification; replacement of rock materials used in the upper and lower layers of the pavement coatings by by-passed stone, utilization of plastics scrap and rubber in polymer modification.
