Sažetak
In highway engineering, consumptive use of natural mineral materials is significant in the construction of new roads, as well as in renovations of the existing ones. A part of this material can be replaced by alternative materials which have been regarded as waste for many years. One such material is fly ash, a byproduct of burning coal in power stations. Its annual output is measured by millions of tonnes just in one power plant, whereas its deposition is spatial, economic and environmental problem. Observing the fly ash as a waste to use-value, the authors conducted a study of its use as a filler in AC 8 surf 50/70 asphalt mixture. Used fly ash belongs to the group of acid fly ash with low content of calcium oxide (CaO). The authors prepared mixtures of several models which are used for optimization of the percentage content of all ingredient mixes which should satisfy the physical and mechanical properties of the General Technical Conditions for road works ; Croatian Road authority.
