Warm Mix Might Be the Trend of Asphalt Mixture Technology

Compared with other asphalt mixing technologies, Mr. Huang thinks that the warm mix has more advantages: without losing the original pavement performance, the mixing temperature can be lowered to 110℃-130℃, while the rolling temperature can reach to 80℃-110℃; the batching, mixing and construction technology of the asphalt mixture are basically the same with hot mix tech; excellent ...

Warm Mix Asphalt - EAPA

Warm Mix Asphalt is an asphalt that is produced and applied at a temperature around 20 – 40 °C lower than an equivalent “Hot Mix Asphalt” (HMA). The information on this website focuses on Warm Mix Asphalt (WMA) technologies for producing asphalt at temperatures slightly above 100 °C with properties or performance equivalent to that of conventional HMA. Thanks to the lower production ...

Warm Mix Asphalt (WMA) mixes are becoming more broadly used with the movement toward an environmentally friendly and sustainable pavement industry. After emerging from Europe in the 1990s, WMA was introduced in the United States (US) in the early 2000s, and since then, it started to replace conventional Hot Mix Asphalt (HMA) mixes. By 2015, WMA mixes comprised about one third of the
