The production of any construction material is energy-intensive, and hot-mix asphalt is no exception. Energy costs constitute a significant percentage of the total cost of HMA production, so conserving energy can improve the bottom line for hot-mix producers. This 32-page publication presents opportunities for energy conservation in the HMA production process, and provides a method to calculate return on equipment investments that might reduce energy-related costs.
