METHOD AND APPARATUS FOR MAKING ASPHALT CONCRETE USING AGGREGATE MATERIAL FROM A PLURALITY OF MATERIAL STREAMS

摘要

A combination of components is provided for use in making asphalt concrete from a plurality of aggregate material streams. The combination includes an indirect dryer for heating aggregate material from a first material stream without directly exposing said first stream material to hot gases of combustion. The combination also includes a mixer for mixing aggregate material from the first material stream, aggregate material that has not been heated in the indirect dryer from a second material stream, and a binder component to produce asphalt concrete.

1. A combination of components for use in making asphalt concrete from a plurality of aggregate material streams, said combination comprising:
(A) an indirect dryer for heating aggregate material having a first top size from a first material stream without directly exposing said first stream material to hot gases of combustion; (B) a mixer for mixing:
(i) aggregate material from the first material stream that has been heated by the indirect dryer;(ii) aggregate material, having a second top size that is larger than the first top size, from a second material stream that has not been heated by the indirect dryer; and(iii) a binder component;to produce asphalt concrete.
