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.

Zbadano wpływ popiołu lotnego klasy C jako zamiennika kruszywa mineralnego na stabilność i gęstość nawierzchni asfaltowych zawierających 3,5−6% mas. bitumu. Dla stężenia popiołu lotnego (w stosunku do zastępowanego kruszywa) 25, 50, 75 i 100% mas. określono optymalną zawartość asfaltu (OAC) odpowiednio 5,75, 4,82, 4,42, 4,4 i 4% mas. Wraz ze wzrostem zawartości popiołu lotnego zwiększała się stabilność nawierzchni asfaltowych. Uzyskane wyniki potwierdzają możliwość zastąpienia kruszyw mineralnych popiołami lotnymi.
