In order to provide meaningful data to quantify the benefits of high-stability asphalt mixtures containing crushed aggregates, a comprehensive lab experiment was designed. The primary goals of this research were to evaluate the role of: 1) size and proportion of coarse aggregate; 2) fine aggregate shape; and 3) increased quantity of mineral filler. Discussion is included.
