ABSTRACT Large quantities of natural materials are traditionally used in road construction. Concurrently the world faces the problem of management of an increasing quantity of waste, so that linking the two problems leads to a simple solution: a growing and more diverse application of waste materials in road building and other areas of civil engineering alike. Road pavement can be considered to be one of the fundamental elements of the transportation system. Significant amounts of bitumen and natural aggregates are used in the construction of asphalt concrete pavements. Waste materials whose application is possible in road construction are divided into three basic groups: re-usable construction materials, industry by-products and natural construction materials of a lower usability value. The first group includes the materials that were used one or more times, such as materials from unbound base courses (gravel, sand, and rock) and materials from bitumen and hydraulically bound layers. Slag is the group of industry by-products, whereas the group of natural construction materials with lower usability value is primarily represented by excavation materials.
