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 ...

The use of Warm Mix Asphalt

2021-6-23  The most important benefit of using Warm Mix Asphalt is the significant lower bitumen fume exposure level during paving operations compared to Hot Mix Asphalt. This lower exposure level supports the goal of the European asphalt industry in reducing bitumen fumes during paving operations to improve the working environment of the asphalt workers.

What is Asphalt - EAPA

Warm Mix Asphalt (WMA) A typical WMA is produced at a temperature around 20 – 40 °C lower than an equivalent Hot Mix Asphalt. Significantly less energy is involved and, consequently, less fumes are produced (as rule of thumb, a reduction of 25ºC produces a reduction of 75% of fumes emission).
