Field Evaluation of Warm-Mix Asphalt Technologies ...

In this study, WMA mixtures containing reclaimed asphalt pavement (RAP) were evaluated in a field project in Ohio. The project included using Aspha-min, Sasobit, and Evotherm in three test sections. Furthermore, a control section was also produced so that a side-by-side comparison could be made between WMA and HMA mixtures.

Evaluating the Effect of Warm-Mix Asphalt

2011-1-1  The effect of warm-mix asphalt (WMA) technologies on the moisture susceptibility of a mixture and the adhesion characteristics of the asphalt binder used in it was evaluated. A 9.5-mm Superpave ® mixture designed with performance-grade asphalt PG 64-22 was used as the control mixture. Four types of WMA technologies were evaluated: Advera, Evotherm, Sasobit, and SonneWarmix.

Laboratory and Construction Evaluation of Warm-Mix

Warm mix asphalt (WMA) describes various technologies that allow asphalt mixtures to be produced at lower temperatures as compared with hot mix asphalt (HMA). WMA technologies also offer improvements in workability, cost, and environmental sustainability, such as reduced fuel usage, greenhouse gas emissions, and wear and tear at plants, while enhancing worker health and safety conditions.
