The Use of Adhesion Additives in Asphalt Concrete with Granite and Slag Crushed Stone

The paper presents the research in adhesion quality of bituminous binders with various types of adhesive additives both with granite and slag crushed stones. The concept of adhesion of a binding substance and stone materials, reasons for their weak interaction as well as a way for efficient increasing the adhesion – the use of special additives – are considered. The aim of the study is to determine the optimum additive for the basic blast furnace slag and granite with acidic nature. In the course of the work, it has been found that both active and passive adhesions are achieved with the use of adhesive additives. In addition, a number of properties of asphalt concrete, as a final composite, improve. Brief characteristics of the tested materials are given, the stages of the experiment conducted are described, visual results of laboratory tests and their analysis are presented.
