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.
