USE OF INDUSTRIAL WASTE MATERIALS IN ROAD CONSTRUCTION IN POLAND

摘要

Protection of environment in Poland has become a very important issue, especially during last years after joining European Union on May 1st, 2004. Strategic motorway construction programme and road network rehabilitation create a field of opportunities for use of waste materials in a large-scale. Although these materials widen range of available road materials, the advantages of their application are not frequently understand. Main problem is that majority of waste materials are not standardized. They may be applied according to technical approvals or individual solutions. In order to increase use of waste materials in Poland, the Road and Bridge Research Institute undertook to development of the catalog of waste materials for road applications. One of the tasks will be the recognition and recommendation for placing material in road construction. Moreover, both technical and environmental specifications for each product will be given. This study includes industrial waste materials, which are available and practically applied in Poland. These materials are divided into 5 groups: slags, power plant wastes (ash and slag), building construction demolition (crushed concrete), mining waste (clump) and chemical waste materials (refinery deposit and crumb rubber-tires). This study collects Polish experience in the field of practical use of waste materials in road construction.
