Abstract & Overview
Introduction. Recycling of secondary production materials is intended to conserve natural resources and reduce the amount of waste that must be disposed of in special landfills. Recycling is very much encouraged in many European Union countries, which have relevant provisions in all waste management directives. A key element in the promotion of waste recycling is the ‘polluter pays’ principle, which has been incorporated into all Community directives on the management of safe and hazardous waste. In order to promote recycling, many Member States have adopted specific environmental legislation, in particular the payment of waste tax. Problem statement. In a market economy and underfunding of the road industry, environmental problems, including industry and depletion of natural resources, are of primary importance for the use of industrial wastes in road construction, while ensuring the operational reliability of layers of road clothing, as well as implementing resource- and energy-efficient measures. In Ukraine, along with natural materials, industrial waste is used as raw materials, which include metallurgical slag, TPP ash, plastic and rubber crumbs. Purpose. Perform an analysis of existing experience in the use of industrial waste in road construction for the further introduction and improvement of operational safety and operational characteristics of road surfaces of Ukraine at the expense of new road construction materials. Materials and methods. Analysis of information sources and experience on the use of industrial waste in road construction and study of material requirements and composition of such mixtures. Results. An analytical review of the experience of using industrial waste in road construction has been carried out. Various materials have been studied and analyzed, requirements for the use of materials, particle size, bitumen content and asphalt mix have been established. Conclusions. The analysis of information sources on the use of waste in the road construction industry shows that industrial waste is used in full in various countries of the world and in most cases in road construction. The use of various wastes on the roads has been found to be a viable option that needs further study.
