Best practice guideline for warm mix asphalt - aapaq.orgWarm mix asphalt defined Warm mix asphalt is the manufacturing and paving of asphalt mixes at significantly lower temperatures than conventional HMA, while maintaining or even exceeding the quality of conventional HMA mixes. WMA can be conveniently classified by the degree of temperature reduction compared to that of conventional HMA.
Warm mix asphalt: an overview - ScienceDirect4. Performance of warm mix asphalt. Since pavement construction with warm asphalt mixes did not begin until the middle of the 1990's (The use of Warm Mix Asphalt., 2010), little is known about the long-term mechanical performance of these mixtures (Kristjansdottir, 2006). In this regard, most of the practical tests to assess the performance ...
Warm Mix Asphalt Final Report - wsdot.wa.govconsumption by allowing the production and placement of asphalt paving mixtures at lower temperatures. These lower temperature asphalt paving mixtures are designated Warm Mix Asphalt (WMA) and can beproduced at temperatures 35-100°F lower than conventional hot mix asphalt (HMA) (Prowell and Hurley, 2013). Potential advantages of WMA include:

Field and Laboratory Investigation of Warm Mix Asphalt in Texasreduction in design asphalt content if incorporated in the mixture design process. Laboratory tests indicate that warm mix asphalt is initially less stiff than hot mix but stiffens considerably during the first year of service and with increases in laboratory oven curing time/temperature. Field performance of warm mix
The Many Benefits of Warm Mix Asphalt - CTIThe Many Benefits of Warm Mix Asphalt You've heard of cold mix and hot mix. Now with the advent of warm mix, we are able to gain the full benefit of hot mix but at a reduced production and placement temperature. There are many benefits to reducing the production and placement temperatures while maintaining the quality of the asphalt pavement.

The use of Warm Mix Asphalt - eapa.orgThe 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.
