Influence of slag, fly ash and silica fume on the mechanical and physical properties of asphalt

摘要

The paper examines the impact of waste materials: slag, fly ash and silica fume on the physical and mechanical properties of asphalt. Natural aggregate fractions from 4-8 mm and 8-11 mm in asphalt were substituted with blast furnace slag while mineral filler was substituted with fly ash and silica fume. Physical and mechanical properties of thus prepared samples were tested according to Standard HRN EN 12697.
