Batch Plant. Batch plants, which produce HMA in individual batches, are the older of the two types of HMA production facilities; it was not until the 1970s that drum plants became a popular HMA production option. Typical batch quantities range from 1.5 to 5 tons of HMA and each batch can take 15 – 45 seconds to make. Figure 5: Batch plant
