A summary of some of the findings obtained during a series of research projects aimed to select, define, and evaluate the significant aggregate and filler properties and relate them to the behavior of bituminous concrete is presented. A concept and test method suggested for an objective quantitative evaluation of the geometric irregularity of aggregate particles (shape, angularity, and surface texture combined) in a wide range of particle sizes are discussed. The aggregate parameters were found to be significantly correlated to the physical properties and mechanical behavior of the bituminous mixtures composed of the aggregates tested. Research work and findings related to a special evaluation of important physicochemical properties of the filler and their significant effect on the immediate properties and the long-term durability behavior of bituminous paving mixtures are summarized.
