为了研究用水量对泡沫沥青抗老化性能的影响，选用了70号道路石油基质沥青和SBS改性沥青，对不同发泡用水量的沥青进行RTFOT及PAV测试，以疲劳因子G*·sinδ作为评价指标，研究沥青的抗老化性能。试验结果表明：70号道路石油沥青随着发泡用水量的增加，极限疲劳温度增加，在常规发泡用水量（1%~2%）条件下，抗疲劳性能略有降低；SBS改性沥青在常规发泡用水量（3%）条件下，抗疲劳性能改善。

In order to probe into the effect of water content on anti-aging properties of foamed asphalt, this study selected 70# asphalt and SBS modified asphalt, carried out RTFOT and PAV experiments on foamed asphalt of dif?ferent water content and then adopted G*· sinδas the evaluation index to research anti-aging properties. Test re?sults show that as water consumption increases, the fatigue limit temperature of 70# asphalt increase and anti-fa?tigue properties decrease in the condition of foaming water content ( 1%~2%),while anti-fatigue properties perfor?mance of SBS modified asphalt increase in the condition of foaming water content(3%).
