SEARCHING FOR THE PERFECT MIX: HMA PLANT DESIGN IS A THREE-PART PROCESS

Hot mix asphalt (HMA) plants must address several issues related to facility design: 1) plant efficiency and cost effectiveness; 2) use of new materials, such as reclaimed asphalt pavement (RAP); and 3) acceptable solutions to actual or perceived environmental damage due to plant operation. This article describes two types of HMA plants--batch plants and drum-mix plants. Although the methods of producing HMA differ, the result is essentially the same. Cost is the overriding factor in the production of HMA and compliance with Environmental Protection Agency regulations generate additional cost for HMA plant owners. Perceived risk is a more difficult issue to address; however, "partnering" with the public to improve the noisy, dirty plant image is changing public perception nationwide.
