Death of the batch plant

During the 1950s, interstate construction required hot mix asphalt (HMA) contractors to increase production capability. Typical batch plant size increased to six tons to meet production demands. Larger screens were added to accommodate the production of multiple mixes. Otherwise, batch plants changed little until about 30 or 35 years ago.

HMA Batch Plant

HMA Batch Plant Batch plants, which produce HMA in individual batches, are the older of the two types of HMA production facilities. HMA was originally made in batches; it was not until the 1970s that drum plants became a popular HMA production option.

Handling RAP in an HMA Facility

Dec 28, 2000 · With the growth of cold milling of HMA pavements as a rehabilitation strategy, production of RAP is estimated at 45 million tons per year. The FHWA estimates that one-third of all HMA removed is recycled into HMA production. Industry experience in the last 20 years has proven that HMA is a resource that can be recycled time after time.

HMA plants are either batch or drum mixer plants. The purpose of both these plants is to mix the right proportions of asphalt and aggregate to meet desired specifications. Figure 2 shows asphalt cement, aggregate, and the asphalt mixture. The batch plant heats the aggregate and mixes it with the asphalt cement in a pug mill.
