• Flaky aggregates is normally avoided in bituminous mixtures, they influence the aggregate gradation, reduce interlocking characteristics, and it should be therefore limited. Indonesian National Standards (SNI) specified a tolerance of flaky aggregate content for a maximum of 25% in Asphalt Concrete mixture for surface course. Gradation was modified into 5 variations of flaky aggregate content, i.e. 5%, 15%, 25%, 35% and 45%. The Marshall test were done with 5 variations of asphalt content such as 5.0%, 5.5%, 6.0%, 6.5% and 7.0%, respectively. Each variation of flaky aggregate content resulted on different optimum asphalt content of 5.85%, 5.90%, 6.0%, 6.05% and 6.15%. Workability Index (WI) measured using gyropac (350 gyrations) at their optimum asphalt content show that the WI decreases with decreasing the flaky aggregate content. The results of Modulus measurement using UMATTA at their optimum asphalt content show that the modulus values decrease when the flaky aggregate content increase.
