The term hot mix asphalt is used generically to include many different types of asphalt–aggregate mixtures that are produced in an asphalt plant. Most commonly hot mix asphalt is divided into the various components and thereafter into three different types of mix depending upon the aggregate: (i) dense-graded mix, (ii) open-graded mix, and ...
typical batch plant is depicted in Figure 5-1; the major plant components are shown in Figure 5-2. The batch plant tower consists of a hot elevator, a screen deck, hot bins, a weigh hopper, an asphalt cement weigh bucket, and a pugmill. The flow of materials in a batch tower is illustrated in Figure 5-3. The aggregate used in the mix is removed ...

A northwest asphalt plant was partially destroyed when it caught fire on a windy spring day. The 6,000-lb batch plant was oriented with the drier running north to south with the hot-stone elevator on the east side. The plant, under the pressure of production quotas, had been operating 16 hours a day for almost two weeks when the accident occurred.
