Effect of the geometrical and physical nature of filler on the rheological properties of mastics
This study investigates properties of mastics produced with 70/100 neat bitumen, three mineral fillers (granite, quartz-granite, and diorite), and a lime-based active filler at filler-to-bitumen (F/B) ratios of 40%, 50%, and 60%. The physical, geometrical, and mineralogical properties of the fillers were assessed. Their influence on mastics' behaviour was evaluated using conventional penetration a
