This paper presents the results of the strength properties evaluation of asphalt concrete produced with sandcrete block powder. Sandcrete block powder (SBP) was used as a mineral filler, while stone dust (STD) filler was used in this research as the control material. Sixteen (16) asphalt concrete specimens were produced with 5 % bitumen, 40% fine aggregate, 60% coarse aggregate, and 2-5% filler proportions by weight of 8 kg. The samples were produced separately in 2, 3, 4, and 5% proportions by weight of each of SBP and STD. The aggregates were properly mixed and stirred while being heated to a temperature of 1000–1200 °C. A total of sixteen (16) cylindrical asphalt concrete samples were produced with 5% bitumen, 2 to 5% fillers (SBP and STD), 40% fine aggregate, and 60% coarse aggregate proportions by weight. Eight (8) samples were submerged in water for 24 hours from the sixteen (16) samples in view. The Marshall stability test examined the flow and stability of the asphalt concrete samples. The results showed that using sandcrete block powder as a filler material increases stability by up to 340%. However, it reduces when the asphalt concrete samples are soaked. The optimum stability value was reached at 2% sandcrete block powder as filler. The sandcrete block powder as filler in asphaltic concrete production should not be more than 3%. Asphaltic concrete's stability and flow results conform to the specifications stated by the Asphalt Institute. This makes the sandcrete block powder suitable for use in asphaltic concrete production.
