Abstract
In the past few decades, warm mix asphalt (WMA) has been used as advanced technology alternative to hot mix asphalt (HMA) due to the relatively low temperatures required heating the asphalt in the production and application process, reducing environmental damage while providing benefits. Asphalt maintains the hot mix, it is noticeable. However, low manufacturing and processing temperatures may result in asphalt deterioration from moisture. The aim of this study was to evaluate the characteristics of asphalt containing natural zeolite and compare it with synthetic zeolite and WMA organic and chemical additives against deterioration against moisture. Resistance properties of samples against moisture sensitivity using tests.
