Abstract
A hot mix asphalt batching plant has two separate air handling systems—one for the dryer and another for handling the fugitive dust. These two systems are separate, so that variations in operating conditions for the dryer do not affect the performance of the fugitive air handling system.

A method for retrofitting a hot mix asphalt batch plant which includes a dryer, a batching tower, and a first air handling system, including a first exhaust fan and ducting connected from said dryer and said batching tower to a first dust collection system, comprising the steps of:
- installing a second air handling system, including a second exhaust fan and a second dust collection system;
- and
- disconnecting the ducting from said batching tower to said first air handling system and connecting ducting from said batching tower to said second air handling system, wherein the air flow through said first air handling system is separate from the air flow through said second air handling system.
A hot mix asphalt facility, comprising:
- a first air handling system including a first exhaust fan and a first dust collector;
- a dryer, including ducting connecting said dryer to said first air handling system;
- a second air handling system which receives fugitive dust generated outside of said dryer, including a second exhaust fan and a second dust collector, wherein said first and second air handling systems are separate.
