Abstract:
Warm Mix Asphalt (WMA) is a new technology which was introduced in 1995 in Europe. WMA is gaining attention all over the world because it offers several advantages over conventional asphalt concrete mixes. The benefits include: (1) Reduced energy consumption in asphalt mixture production process; (2) Reduced emissions, fumes, and undesirable odors; (3) More uniform coating of aggregate with binder, which should reduce surface aging; and (4) Extended construction season in temperate climates. WMA requires the use of additives to reduce the temperature of production and compaction of asphalt mixtures. WMA technologies include: Aspha-min, the addition of sodium aluminum silicate or zeolite to the asphalt mix; Sasobit, the addition of a paraffin-wax compound extracted from coal gasification; Evotherm, the addition of an emulsion to improve the coating and workability of WMA mixes.
