USING THE METHODOLOGY OF "GREEN" CONSTRUCTION FOR RATING EVALUATION OF ROADS

Abstract

The use of new technologies and raw materials, including man-made materials, in the production of con-struction and road materials increases the risks of forming a negative technogenic load on environmental objects when used in road construction. This is of particular relevance due to the fact that the road network has a long extension in the settlements and as a result has a negative impact on the person. A new methodolo-gy for "green" construction, which is currently being effectively used in a number of developed European countries, can give a comprehensive assessment of the emergence of risks. On the basis of analytical and la-boratory studies it is shown that the methodology of "green" construction used for the evaluation of residen-tial and industrial buildings can not be applied to the evaluation of road construction objects. When as-sessing the building materials used in road construction, the change in their physicochemical condition dur-ing long-term operation in the elements of road structures is not taken into account. It is shown that the emis-sion of environmentally hazardous chemical compounds that make up construction materials increases with the cyclicity of the pH of the medium of their placement, the discontinuity of the surface. It was proposed to include such provisions as "protection from the aquatic environment", "stable pH values of the external envi-ronment" for the formation of a rating system for assessing the "green" construction of motor roads in order to ensure environmental safety.
