Title of Invention
Cold asphalt mixture containing recycled aggregate and one-part liquid type emulsified asphalt and the method for manufacturing the same
Description
Unlike the conventional two-part liquid type in which the additives are mixed after the emulsified asphalt and the recycled aggregate are mixed, this one-part liquid type to which the emulsified asphalt is added in advance allows for an easy mixture of the emulsified asphalt with the recycled aggregate even with the addition of a small amount of additives, and the one-part composition also enables the manufacturing facility to be simpler and more effective.
