Warm Mix Asphalt - EAPA

Additives were trialled in Germany and in Norway the WAM-Foam® process was developed. Figure 1 shows how WMA fits into the full range of techniques from cold mix through to hot mix: Figure 1: Classification by temperature range Cold mixes are produced with unheated aggregate and bitumen emulsion or foamed bitumen. Half Warm Asphalt is produced between approximately 70 °C and

Mix Design Practices for Warm-Mix Asphalt

This effect, how- ever, may be offset by the addition of warm mix additives and the effect that these additives and water have on binder aging. The lower production temperatures may also limit the types and quantity of recycled asphalt materials that can be used in WMA. Design of HMA assumes substantial mixing of new and recycled binders, which may not be possible at the lower production ...
