Plant - A hot mix asphalt (HMA) plant is the facility that is used to produce HMA. HMA paving materials are a mixture of size-graded, high quality aggregate (which can include reclaimed asphalt pavement (RAP), and liquid asphalt cement, which is heated and mixed in measured quantities to produce HMA. An HMA plant can be constructed as a
