Introduction. The implementation of the Weighing in Motion System (WIM) in Ukraine has been started in compliance with the State Targeted Economic Program for the Development of Public Highways of State Importance in 2018-2022 and was aimed at preserving the road surface from damaging and reducing expenses for road maintenance. In order to ensure transparency in the field of state planning for the road construction, reconstruction and repair, Ukravtodor ensures the publication of up-to-date WIM information via interactive map http://bit.ly/wiminbrief and annual statistical reports. The paper describes an analysis of traffic volume coefficients based on WIM data. Problems. The need for improving the method of calculating of road pavement structures (non-rigid and rigid) reliability under existing traffic loads, taking into account the WIM data on traffic volume and traffic condition. Purpose. Clarification of traffic conditions and traffic loads on road pavement. Materials and method. Mathematical modelling using survey data. Results. Up-to-date traffic volume coefficients. Conclusions. The implementation of WIM System and WIM sites network expansion is a progressive way for traffic volume and traffic load monitoring and reducing destructive impact of overloaded vehicles on road pavement. WIM data is suitable for traffic load modelling loads and road pavement designing.

It is known that all production resources are limited and rare. This economic problem is especially acute for such major components of natural resources as land, forest resources, mineral deposits, water resources, wildlife, which people use in the production of various goods and without which economic activity is impossible. The planning, construction and operation of roads should be carried out in accordance with environmental standards, and the standards themselves should minimize the impact of road networks on the environment. The high level of concentration of heavy industry, unreasonable scale of land reclamation, environmental voluntarism in the development and location of productive forces and the financing of environmental measures on a residual basis lead to an ecological crisis. The effects of economic activity have led to the pollution of vital resources and the degradation of the environment. This article identifies the nature and extent of the main types of environmental impacts during the overhaul of the facility and its subsequent operation. Measures to prevent negative impact on the environment, such as: rational use of land and natural resources, protection of atmospheric air. Ways and means of normalization of the state of the environment, the main source of which on the highway are directly vehicles and road vehicles are considered. The amount of harmful emissions and the distance of their spread varies depending on the intensity and composition of traffic, road, natural and climatic conditions. In the process of existing potential types of environmental impacts is the impact on ambient air. On the geological environment, microclimate, aquatic environment, soil, flora and fauna. The impact on the environment of the road section after major repairs is permanent and is not harmful provided they are harmoniously combined with nature.
