Abstract

Warm Mix Asphalt (WMA) technologies have made a considerable development in recent years, where studies on environmental pollution and protection of natural resources have become prominent all over the world. Thanks to the rapidly developing and renewed WMA technologies, nonrenewable resources can be saved while environmental effects caused by asphalt production can be reduced. In recent years, WMA technologies have begun to gain importance in the production of Hot Mix Asphalt (HMA), particularly in developing countries where energy supplying is quite expensive for economic reasons. In this study, Stone Mastic Asphalt (SMA) was produced by using pure and modified bitumen with three different WMA admixtures. Marshall tests were carried out to examine the design parameters of these samples. As a result, Marshall Design parameters of Warm Mix Stone Mastic Asphalt (WM-SMA) blends have been produced with WMA additives by decreasing the construction temperature. The resulting mixtures fall within specification criteria.
