| 摘 要： | 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。

| Abstract: | 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 different water content and then adopted G＊·sinδas the evaluation index to research anti-aging properties. Test results show that as water consumption increases, the fatigue limit temperature of 70# asphalt increase and anti-fatigue properties decrease in the condition of foaming water content （ 1%-2%）,while anti-fatigue properties performance of SBS modified asphalt increase in the condition of foaming water content（3%）. |
