There has been a focus on the effective utilization of sewage sludge ash from Iwate Prefecture as filler for asphalt mixture. This ash can partially replace limestone filler, and if it is used as-is after being expelled from a treatment facility, the optimum asphalt content increases as the replacement ratio increases, reducing various properties of the asphalt mixture. However, with a replacement ratio up to 45%, all criteria are met and it can be applied. On the other hand, reduced properties cause porous ammonium magnesium phosphate particles to generate eccentrically in the coarse regions. If these coarse areas are eliminated, the various properties of the asphalt mixture can be improved.
