Abstract: Aggregates are important constituents of pavement structures. The performance of aggregate layers depends on particle shape, grading and composition and their physical, mechanical and chemical properties. Careful study of these properties allows evaluation of aggregates according to the international norms. There are the huge aggregate reserves around Negotin, Serbia. With a growth of construction in and around Negotin, the demand for aggregates has become so high that the limited quarry sites within the valley are not sufficient to meet the demands. Therefore, by searching for rock outcrops from which the suitable aggregates can be extracted, it is sought to meet the current and future needs of aggregates suitable not only for building and infrastructure, but also for roads or transport networks in the country. This study aims to research and evaluate the suitability of natural disintegrated, that is, crushed rock aggregates in the area Paunovac near Negotin, Serbia the unbound parts of the pavement structure. Disintegrated siltstones and calcareous siltstones were mainly identified in the research area.
