Abstract :

This study investigates the suitability of using Municipal Solid Waste Incinerator (MSWI) ash as fine aggregate in Hot Mix Asphalt (HMA). HMA design was carried out, using Marshall Stability method. Fifteen (15) samples were prepared and compacted for strength and volumetric properties testing at varying bitumen contents of 5.0%, 5.5%, 6.0%, 6.5% and 7.0% to obtain the Optimum Bitumen Content (OBC). The investigation focuses on the partial replacement of fine aggregate with MSWI ash using the obtained OBC in the following order 10%, 20%, 30%, and 40%. A total of twelve (12) mix specimens were prepared to determine the optimum MSWI ash content in terms of the HMA strength. From the Marshall Stability-flow test analysis, the sample prepared with 20% MSWI ash as fine aggregate with an OBC of 5.5% satisfied the provision of the Standard Specification requirement by Nigerian Standard Specification for Roads and Bridges for use in wearing course of flexible pavement.
