PRETREATED AGGREGATE FOR HOTMIX ASPHALT CONCRETE APPLICATIONS AND OTHER RELATED APPLICATIONS.

摘要

A process of producing an asphalt concrete with enhanced performance is providedby utilizing a primer. The primer is added to a hot aggregate with a surface temperatureof at least 250 deg. F prior to addition of an asphalt-derived base binder. Theprimer forms a primer interlayer between the hot aggregate and the base binder.As a result, the asphalt concrete has enhanced performance when compared withother asphalt concretes produced without a primer being added.
