Statement of the problem. The state of theoretical studies in the field of engineering and landscape zoning is detailed. Results. The analysis made it possible to outline the goals, objectives and the general methodology of research and modeling of organization and planning processes for the construction of departmental roads considering micro-landscapes, varying degrees of complexity of road construction, value of natural resources, species qualities of a road area as well as to optimize the design process of departmental highways.Conclusions. The suggested comprehensive assessment of the natural and technogenic conditions for the construction of departmental highways is gaining economic, technical and environmental significance and can be employed as the basis for landscape design of departmental highways.

Statement of the problem. A method for the construction of drainage pipes in road construction using the technology of arranging coiled pipes from polymer profiles with a metal core is considered. This technology has some unique properties and characteristics that make it possible to bring road construction to a new technological level. Results. In the course of the study, an analysis of the spiral-wound technology for the construction of pipes was performed, the three most common technologies for the device of spiral-wound pipelines were considered in detail. A comparative analysis of the effectiveness of spiral-wound technologies in terms of characteristics, labor costs and cost of work is provided. Conclusions. Spiral-wound technology is the most promising and optimal for road construction. The design features of the culverts built using this technology have no restrictions on the form factor, they allow one to arrange pipes of a wide range of diameters. The installation of ten meters of a coiled pipeline in a closed way is almost 3 times more efficient than that of a similar metal pipeline, requires 1.86 times less money, and is environmentally efficient. Adaptation of methods for calculating and designing pipelines to the features of spiral wound technologies will speed up and simplify the design and construction of culvert pipelines as part of the roadway.
