摘要
为了研究发泡用水量对基质沥青与RET改性沥青感温性影响,以复数模量指数（CNI）为评价指标,进行动态剪切流变试验（DSR）。试验结果表明：70#道路石油沥青随着发泡用水量的增大,温度敏感性提高,在常规发泡用水量（1%-2%）条件下,温度敏感性得到改善;RET改性沥青随着发泡用水量的增加,温度敏感性降低,在常规发泡用水量（3%）条件下,温度敏感性稍有降低。
In order to study the influence of foaming water consumption on the temperature susceptibility of base asphalt and RET modified asphalt,a study of dynamic shear rheometer（ DSR） is done,being complex modulus index（ CNI） as the evaluation index. The results show that 70#road petroleum asphalt improves the temperature susceptibility with increase of foaming water consumption; in conventional foam with water（ 1 - 2%） consumption,temperature susceptibility is improved; but RET modified asphalt＇s temperature susceptibility decreases with increase of foaming water consumption,in conventional with water（ 3%） consumption,temperature sensitivity decreases slightly.
