• 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.
