HMA was originally made in batches; it was not until the 1970s that drum plants became a popular HMA production option. Currently about 70 percent of all operational HMA plants in the U.S. are batch plants while about 95 percent of all newly manufactured plants in the U.S. are drum plants (Roberts, et al., 1996 [1]). This means that as older ...
