Sažetak
Guidelines for sustainable development stipulate protection of non-renewable sources of natural aggregates, which means creating the best and most cost-efficient application of all available resources. Very large quantities of natural aggregates are used in civil engineering ; a significant part of those quantities is particularly used for purposes of road building. Natural aggregates which are used in large quantities in road building are crushed stone, excavated gravel, and river gravels and sands. Such a continual demand for natural materials depletes natural sources, and the costs of procurement and transportation in areas with scarce good quality aggregates significantly increase building costs. Therefore, waste materials may be significant as an alternative in road building in a number of ways. Large quantities of waste materials are a product of demolition of buildings, and particularly re-deposition of such materials has been recognized as a possibility for preservation of natural sources of materials, such as reduction of energy required for the production of natural aggregates and a manner in which it is possible to reduce the surface size of the landfill where waste material is deposited. In some European countries it is even the standard alternative for road building and maintenance, especially if the country has scarce natural aggregates. The paper describes examples of successful incorporation of material which is a product of removal of existing buildings at two sites in residential areas Špansko-Oranice in Zagrebu and Sopnica-Jelkovec in Sesvete (in Croatia). Recycled construction material was embedded into pavement base courses of road at the same site where it was „produced“. Tests of modulus of compressibility of the deposited base courses were carried out, and the obtained results had higher values than the values of the modulus of compressibility required by the design.
