A certain percentage of fine aggregate (less than 74 micrometers [μm] in physical diameter) is required for the production of good quality HMA. Hot mix asphalt paving materials can be manufactured by: batch mix plants, continuous mix (mix outside dryer drum) plants, parallel flow drum mix plants, and; counterflow drum mix plants.
to determine whether the HMA operation is balanced compares the plant production to the rate of mixture required to be delivered to the jobsite and the actual paver production rate to the effective compaction production rate (Figures 4-2 to 4-4). The following example explains the procedures required to balance the HMA operations. Example

Jan 16, 2015 · First you have to decide which type to go for. The basic types are batch type and continuous type. Batch type makes HMA in batches and the latter makes HMA in a continuous process. But the difference is not just as simple as this. There is a whole lot of difference in the process of the batching plant vs asphalt drum mixers.
