Abstract

The use of coal as fuel in steam power plants creates problems for the environment because the residual combustion produces solid waste such as fly ash and bottom ash. This study aims to determine the value of the Marshall parameters in asphalt-concrete mix due to the use of coal bottom ash (CBA) to substitute fine aggregate. Aggregates used were taken from Indrapuri, Aceh Besar District. Variations in CBA are 5% and 15%. This study uses the Marshall method. The results obtained from this study show that the best CBA content is 5% with 6.05% asphalt content. The durability of asphalt concrete mix without CBA is 98.29% and the asphalt concrete mix using 5% CBA content is 96.11%, respectively. Thus, the durability value is ≥ 90%, this indicates that the durability value fulfills the 2020 Bina Marga specifications.
