AASHTO M 156-13 (2017) is a standard specification that outlines the requirements for mixing plants that produce hot-mixed, hot-laid bituminous paving mixtures. The standard provides guidance on the production of both hot mix asphalt (HMA) and warm mix asphalt (WMA) paving mixtures. These specifications can be used as a basis for state certification or for the inclusion of an asphalt mixing plant on an Agency's approval list. It is important to note that additional requirements may be specified by the Agency in addition to the requirements outlined in this standard. The purpose of this standard is to ensure that the mixing plants meet the necessary criteria for producing high-quality bituminous paving mixtures.
