of asphalt plants. Asphalt Concrete plants are basically of two types, batch or drum mix. The two types of asphalt plants derive their names from their particular type mixing operation. In the batch-type mixing plant, hot aggregate and asphalt are withdrawn in desired amounts to make up one batch for mixing. After mixing, the thoroughly mixed material is discharged from the pugmill in one batch. In the drum-type mixing plant, the aggregate is dried,
Asphalt Pavers: The asphalt paver is a self-propelled formless laydown machine with a floating screed. Hot Mix Asphalt is loaded in the front, carried to the rear by a set of flight feeders, spread out by a set of augers, then leveled and compacted by a screed. This set of functions can be divided into two main systems:
