Abstract

Buton asphalt is a natural resource owned by Indonesia. One of the Buton asphalt processed is Retona Blend 55 Asphalt. Due to the abundant stock and better quality, Retona Blend 55 Asphalt can substitute Pertamina asphalt. Besides buton asphalt, Indonesia also owns coal mostly used for steam power plants. Coal fly ash has a size passing sieve number 200 and a hydrophobic profile. Thus, the authors utilized coal fly ash as the filler in the concrete asphalt mixture and Retona Blend 55 as the binder. The experiment employed the Marshall method to determine the effect of using coal fly ash as the substitute material of several fillers. The test results obtained 6% KAO with the filler application of 3%, 3.5%, 4%, and 4.5%, decreasing VMA, VIM, Marshall Quotient, and Stability. Moreover, the VFA, flow, and density values increased compared to testing without coal fly ash.
