摘要

研究了C类粉煤灰作为矿物骨料的替代品对沥青含量为3.5-6wt%的沥青混合料的稳定性和密度的影响。对于粉煤灰浓度（相对于更换的集料）25、50、75和100wt%，确定了最佳沥青含量（OAC），分别为5.75、4.82、4.42、4.4和4wt%。稳定性随粉煤灰含量的增加而增加。结果证实了用粉煤灰代替矿物骨料的可能性。

Class C fly ash as a substitute for mineral fillers in asphalt mixtures

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.
