Figure 11.1-1 shows the batch mix HMA production process. Raw aggregate normally is stockpiled near the production unit. The bulk aggregate moisture content typically stabilizes between 3 to 5 percent by weight. Processing begins as the aggregate is hauled from the storage piles and is placed in the appropriate hoppers of the cold feed unit.
