再生沥青混合料强度及疲劳性能试验研究

Experimental Study on the Strength and Fatigue Performance of Recycled Asphalt Mixture

从高温强度即高温抗变形性、低温强度和低温抗裂性、抗疲劳性能3个方面对不同再生沥青添加量对混合料强度和疲劳性能的影响进行了研究。发现,再生沥青含量越高,混合料高温抗变形性越好,低温强度也越高,但再生沥青含量越高,其低温抗裂性和抗疲劳性能越差。

In this paper, effects of different recycled asphalt additions on the strength and fatigue properties of the mixture were studied fi＇om 3 aspects, such as high temperature strength （ also called high temperature resistance to deformation, low temperature strength and low temperature crack resistance, and fatigue resistance. It is found that the higher the recycled asphalt content is, the better the high temperature deformation resistance and low temperature strength of the mixture are. But the higher the recycled asphalt content is, the worse the low temperature crack re sistance and fatigue resistance are.
