This research investigates the manufacture and properties of controlled low-strength materials (CLSM) that were produced using bottom ash (BA) as fine aggregate (F). Mixtures of CLSM were prepared with various volume ratios of F-to-BA (100/0, 90/10, 70/30, and 50/50) and a constant amount of 5% cement, 10% slag, 82% fly ash and 3% CaCL₂. CLSM mixtures were prepared at an initial ratio of water to powder (w/p) of 0.35 and added water to obtain the flow of 30±2cm. The properties of CLSM were evaluated by relevant standards.  The experimental results show that the flow of all CLSM mixtures met high flowability requirements under ACI 229R. Using BA as fine aggregate reduced the fresh unit weight of CLSM but delayed the setting time. Moreover, CLSM mixtures could serve as a re-excavation and pavement subbase.
