This research investigates the use of incinerator ash as a partial replacement of fine aggregate in hot-mix asphalt concrete. Municipal solid waste (MSW) Incinerator ash was obtained from an incinerator facility at Sultan Qaboos University in Oman. Physical and chemical characterization of the ash was performed. MSW ash was used in the mixture to replace fine aggregate with a percentage ranging from 0 to 40%, by total aggregate weight. The mixes were designed using the Marshall mix design method. The dynamic modulus test was conducted on 4 by 8 inches samples prepared at optimum asphalt contents for mixes containing different percentage of ash. The test was conducted at different temperatures and frequencies. Master curves for different percentages of ash in the mix were developed from the testing results.
