Different characteristics of aggregates has significant impact on the high modulus mixture properties of hard asphalt (such as high temperature properties, modulus, and fatigue resistance). This paper chooses two kinds of aggregates (basalt and limestone) with obvious differences. Based on the Aggregate Image Measurement System (AIMS), this paper made detailed comparison and analysis on all characteristics of the two kinds of aggregates. Referring to the French high modulus mix design process, the various performance indicators coordinated design methods were tested on the high modulus mixture of hard asphalt. Results show that, it can be achieved a balanced design of high temperature performance, modulus, and fatigue resistance properties on the mixture thronging the gradation and the hard asphalt dosage adjustment, for different properties aggregate.
