摘要
To provide a recycled asphalt mixture manufacturing method and recycled asphalt mixture capable of exhibiting further excellent durability.SOLUTION: A recycled asphalt mixture manufacturing method includes the steps of: adding a regeneration additive and/or a workability improving agent to an asphalt recycled aggregate a by an injector at normal temperature or by heating; and curing the asphalt recycled aggregate a for 3 days or more. Thereby, the regeneration additive and/or the workability improving agent penetrate(s) deeply into the old asphalt and improve(s) the properties of the asphalt recycled aggregate a. The cured asphalt recycled aggregate a is dried by heating. Then, the asphalt recycled aggregate a is charged into a mixer 5 together with a novel coarse aggregate b, a fine aggregate d, a filler such as stone powder, and a novel asphalt c, and mixed, whereby a recycled asphalt mixture A can be manufactured.SELECTED DRAWING: Figure 1
