A significant growth has been shown in recycling of the old asphalt pavement as a technically and environmentally preferred way of rehabilitating the existing pavements during the three decades. However, savings acquired by using this technology may be lost through excessive maintenance processes if the recycled pavement exhibits too much deterioration.

recycling technique combining both warm mix asphalt (WMA) and recycling techniques may well compensate for this deficiency. Adding appropriate warm mix agent during the hot recycling process can effectively reduce mix, paving, and compaction temperatures over 30°C. One advantage is to increase the utilization ratio and to
