ABSTRACT:
A compact, enclosable plant for producing hot mix asphalt from various ingredients, including recycle asphalt pavement ("RAP"). The system includes an inclined rotary drum, a burner assembly for generating a hot gas stream within the drum; a baghouse, exhaust blower, and stack mounted above the drum for reclaiming entrained particulate matter; an auger arrangement for returning the reclaimed particulate matter to the: and a supporting frame. The baghouse has a lower chamber for collecting the reclaimed particulate matter and for serving as a primary hopper for certain of the various ingredients. A plurality of preferably rectangularly shaped storage and loadout silos for containing certain of the ingredients and the hot mix asphalt, and conveyors for conveying the certain ingredients and hot mix asphalt to and from the storage and loadout silos, and to a bypass chute for direct loading on transport vehicles. The system is compact such that lengths of conveyors and ducting interconnecting the baghouse and drum can be minimized, and such that the system can be enclosed to minimize noise and odor pollution and to provide an esthetic appearance. The system may be configured in either a counterflow configuration or a parallel flow configuration.
