Abstract: The fine-grained waste mineral materials is used in the recycling technology with foamy bitumen as mineral filler from 5% to 20% in the aggregate mix. This allows its use of mix recycling, fine-grained waste mineral materials from the dedusting system of aggregate in coating plant and during the production of aggregates in mines (whilst crushing the rocks and rinsing the aggregate). In this investigation three different fine-grained waste mineral materials (dolomite, gabbro, and quartzite sandstone) were tested the basic functional properties were defined i.e. pH - acidity - alkalinity, Blaine's actual area Pw, the contents of clay minerals - with the use of methylene blue indicator MBF and determination of the voids of dry compacted filler. The fine-grained waste mineral materials are in proportion of 10%, 15% and 20% to mineral mix. From the analysis, which was within the domain of stability and flow (Marshall), indirect tensile stretch (ITS) and water resistance (TSR), the dependency of functional properties of fine-grained waste mineral materials on the mechanical basecourse properties in recycling technology with foamy bitumen was defined. The possibility of utilization of fine-grained waste mineral materials in the recycling technology of deep cold with foamed bitumen, substantially affect the protection of the environment. At the same time it preserves the required properties of recycled pavement.
