Abstract
The influence of class C fly ash as a substitute for mineral aggregate on the stability and density of asphalt mixtures containing 3.5−6 wt% of bitumen was investigated. For the fly ash concentration (in relation to the replaced aggregate) 25, 50, 75 and 100 wt%, the optimal asphalt content (OAC) was determined, respectively, 5.75, 4.82, 4.42, 4.4 and 4 wt%. The stability increased with the increase in the content of fly ash. The results confirm the possibility of replacing mineral aggregates with fly ash.
