Construction and Demolition Waste Usage Possibilities

Construction and demolition waste with certain treatment procedures can be effectively used for different applications – as material for roads bearing layer as well as an addition for various concrete and asphalt mixtures. It is well known that this usage directly affects on environmental protection, saving the natural resources. In order to achieve necessary requirements for an appropriate disposal, recovery and storage of construction and demolition waste, certain methods and procedures should be specified. In this paper are presented requirements and recommendations for using raw material obtained from C&D waste, and in particular characteristics of recycled aggregate. Physical and mechanical properties of recycled aggregate depend on waste origin, separation procedures and material treatment. Possibilities of its usage mostly depend on user requirements and for that purpose, specific properties of recycled aggregate in comparison with aggregate from natural resources should be clearly defined. In general, the whole system of C&D waste management should be supported by legislation relating to the building design and issuance of location and building permits. It is necessary in order to increase use of environmentally friendly materials, to discourage generating of new construction waste, and to include construction waste management options in design documents.
