WMA technologies allow production plants to produce HMA at Fahrenheit temperatures 45 degrees to 85 degrees lower than the traditional mixing temperature. All personnel responsible for HMA should familiarize themselves with this publication. 22), published for sale by the Asphalt Institute, contains information on the uses of types of asphalts and the design and production of HMA.

Section 39 also provides construction requirements for work on existing asphalt concrete facilities.Īll requirements including smoothness requirements in Section 39, except those in Section 39-3, “Existing Asphalt Concrete,” of the Standard Specifications, apply to all types of HMA.Ĭonstruction of Quality Asphalt Pavements (Manual Series No.
Unless WMA is specified, the term “hot mix asphalt” refers to all mixtures of aggregate and asphalt regardless of the mixing or placing temperature. Section 39, “Asphalt Concrete,” of the Standard Specifications provides material and construction requirements for hot mix asphalt (HMA) including Type A, rubberized hot mix asphalt-gap graded (RHMA-G), open-graded friction course (OGFC), minor HMA, and hot mix asphalt with warm mix asphalt (WMA) additive technology.
