<![CDATA[Utilization of fly ash which is part of the residue from burning coal for power plants (PLTU), where the combustion products have the same size as sand. Asphalt concrete is a type of construction pavement consisting of a mixture of asphalt and aggregate, either with or without added materials. This research aims to determine the characteristic values of asphalt using fly ash as a substitute for sand in AC – WC asphalt concrete with mixed variations of 25%, 50% and 75%. From the research results, the AC-WC mixture used according to the standard, namely the condition of 5.5% asphalt content, obtained a stability value of 1580kg, a VFB value of 79.00%, a VMA value of 15.50%, a VIM value of 3.40%, a MQ value of 550kg/mm , flow value 2.90mm and density value 2.35. Tests with mixture variations of 25%, 50% and 75% obtained a maximum stability value of 1706.5kg at a variation of 25%, a maximum flow value of 3.54mm at a variation of 75%, a maximum VIM value of 6.90% at a variation of 75%, a maximum VMA value 17.68% at 75% variation, maximum VFB value 84.89% at 25% variation, maximum density value 2.38 at 25% variation and MQ value 605.33kg/mm at 25% variation. From the results of a study of the characteristics of asphalt using fly ash as a substitute for sand in AC-WC concrete asphalt with a variation of 50% which meets the requirements of the 2018 General Specifications Revision 2.]]>
