摘要：

With increasing concerns of global warming and increasing exhaustion of greenhouse gases, the asphalt industry is looking for alternatives of hot mix asphalt (HMA). Reasonable solution is a use of warm mix asphalt (WMA) technologies, which allows to reduce asphalt mixing and working temperatures. The advantages of WMA are reduced energy consumption, reduced emissions and improved workability. This article presents the overview of different WMA production technologies, advantages and disadvantages of these technologies. Water bearing, chemical and organic additives were used for WMA production and temperature of produced asphalt varied from 150 degrees C to 120 degrees C. Results of experiment for selection of optimal amount of temperature lowering additives and their influence to physical mechanical characteristics of asphalt mix are presented too.
