ABSTRACT
In recent years, warm mix asphalt (WMA) is becoming more and more used in the
asphalt industry. WMA provide a whole range of benefits, whether economic,
environmental and ecological. Lower energy consumption and less pollution is the most advantages of this asphalt mixture. Paper deals with the addition of natural zeolite into the sub base asphalt layers, which is the essential constituent in the construction of the road. Measurement is focused on basic physic – mechanical properties declared according to the catalog data sheets. Aim of this article is to demonstrate the ability of addition the natural zeolite into the all asphalt layers of asphalt pavement. All asphalt mixtures were compared with reference asphalt mixture, which was prepared in reference temperature.

Keywords: natural zeolite, warm mix asphalt, temperature
