The construction of asphalt roads has been commonly used as for infrastructure development since ancient times. The production of asphalt using drum mix plants has created powder waste in the premix batching plant industry. It consists of very fine powders and causesproblems to the environment today. However, powder waste can be successfully and economically utilized in the development of self-compacting concrete (SCC). The aim of this study is to evaluate the fresh properties and the compressive strength of SCC containing asphalt dust waste (ADW). For this purpose, a simple modified volumetric mix design approach based on the Okumura Method was adapted to produce SCC mixes. In order to obtain this SCC, a series of SCC mixes with a specific water/binder ratio (0.3), superplasticizer ratio (2%) as well as different amounts of aggregate, sand and ADW were prepared. Fresh properties of the SCC mix were tested using tests such as slump-flow, J-Ring, L-box and V-funnel which showed satisfactory results for MD840 and MD850. The compressive strength for MD840 and MD850 after 28 days was 40.8 MPa and 34.7 MPa respectively. In conclusion, the simple modified volumetric mix design method by utilizing ADW in SCC can be suggested for the development of SCC.
