Ecological features of handling objects of the road construction complex

Introduction. The active development of the transport network of highways is one of the areas of construction activities, the environmental safety of which does not fully comply with environmental requirements. The road transport complex has a negative impact on all existing components of ecosystems, but the greatest impact is associated with the formation of waste generated during the reconstruction of highways. To minimize the negative impact of the road construction complex waste management on environmental components, it is necessary to supplement the well-known methods of assessing the created schemes and methods with approaches associated with the analysis of environmental safety. Materials and methods. Due to the fact that most of the waste generated during the reconstruction of highways is multi-composite, a classification by enlarged types is proposed, depending on their chemical composition and state of aggregation. Results. For the numerical assessment of the biopositivity parameter in the comparative analysis of various technologies, the method of hierarchy analysis was tested, which is based on the principles of decomposition, pairwise comparisons and synthesis of priorities. In general, the assessment of biopositivity is a hierarchical procedure that includes operations related to the transformation of the scale and its aggregation. The most significant factors reflecting the impact of the technologies under consideration on the environment were selected as the criteria for the assessment. Conclusions. The presented calculations of the biopositivity parameter for the considered methods of reconstruction of highways in swampy areas showed that the peat technology has the least impact on the environment. The bio-positivity index during peat extraction is 2 times higher than when using geocontainer processing of wetlands.
