摘要：
The paper presents the research and experiments realised in order to obtain ecologically sustainable asphalt mixtures. The preparing and laying temperature is lowered with the help of an admixture. The energy consumption is also reduced. From the ecological point of view, this method reduces the amount of noxious agents produced by heating the bitumen and the natural aggregates and in the process of laying the asphalt mixtures. The preparation-of the asphalt mixtures is realised at about 140-155 degrees C, and the laying at 120 degrees C and compaction at 90-100 degrees C. The experimental section realised on IV 665 Tg. Jiu (Curtisoara)-Novaci-Baia de Fier-Polovragi, the Gorj county, justifies the ecological, technical and economical efficiency of the ecologically sustainable asphalt mixtures.
