Warm Mix Asphalt TechnologiesWarm mix asphalt (WMA) technologies are being promoted . throughout the United States for their ability to lower the production and placement temperatures of conventional hot mix asphalt (HMA). From an environmental standpoint WMA has the potential to lower asphalt production temperatures which can equate to reduced energy consumption, and
Warm Mix Asphalt – Gaining momentum | Asphalt magazineWarm mix asphalt (WMA) is the latest high impact innovation in the asphalt industry. Surprisingly, WMA is not a new mix or materials system. At the most basic level, it is a means of producing an asphalt mix without heating the aggregate to the normal hot mix asphalt (HMA) levels.
Understanding the differences between hot mix asphalt and ...Warm mix asphalt or WMA is currently used in about 30 percent of all paving projects. WMA is manufactured at temperatures between 200 and 250 degrees Fahrenheit. It uses less fossil fuels and resources in its manufacturing process and includes additional binding materials and additives, including wax, emulsions and zeolites for easier pouring and spreading at low temperature.
