BASIC PRINCIPLES OF DESIGNING OPTIMAL ROAD STRUCTURES WITH SHALL LAYING DRAINAGE

Andrii Bubela

Uncontrolled movement of heavy vehicles, violations of construction technology and deficiencies in road design cause premature destruction even on newly built and extensively renovated roads. Destruction of coatings in many cases is associated with overmoistering of the ground surface and road foundations due to the unsatisfactory state of drainage and drainage structures or their complete absence. Cracks, which are the root cause of potholes, cause serious danger and high additional costs associated with road maintenance. Depending on the type of moistening of the working layer of the subsoil, soilhydrological and climatic conditions, the topography of the area, the availability of road construction materials, options for drainage structures are assigned. Problem Statement. The installation of drainage structures determines the need to solve the urgent problem of water drainage from the road structure at three interrelated stages: design, construction and operation of the road. Such design decisions require the search for optimal options for road structures according to the relevant criteria, but the problem of their substantiation is not given due attention. The purpose of the work is to form the basic principles of designing optimal road structures due to the proposed measures to regulate their water-thermal regime. Materials and methods: analytical and statistical methods; methods of mathematical modeling. Results: the work investigated the methodological structure for choosing the optimal road structure: clarification of the purpose of construction, search for possible optimal options, establishment of optimality criteria, determination of resource costs by options, obtaining the optimal solution, final selection of the optimal road structure. Conclusion. The design of optimal road constructions with transverse drainages of shallow laying is based on the principles of ensuring the strength, frost resistance and sliding resistance of the road surface under the condition of minimal reduced construction costs
