摘要: 为了研究不同发泡条件下泡沫沥青的降黏效果,选择70#基质沥青和SBS改性沥青,进行正交试验。对不同发泡条件下泡沫沥青的黏度进行研究,结果表明:基质泡沫沥青降黏效果影响程度为:发泡用水量>发泡温度>发泡水温,在发泡温度为150℃,用水量为3%,水温为20℃的条件下70#基质泡沫沥青降黏效果最优。SBS改性泡沫沥青降黏效果影响程度为:发泡温度>发泡用水量>发泡水温,在发泡温度为160℃,用水量为3%,水温为60℃的条件下SBS改性泡沫沥青降黏效果最优。

Abstract: In order to study the viscosity reduction effect of the foamed asphalt under different foamed conditions, 70# conventional asphalt and SBS modified asphalt were selected to do the orthogonal experiment. After the studies on the viscosity of the foamed asphalt under different foamed conditions, the results are as follows: the influence degree of viscosity reduction of 70# conventional asphalt is water consumption>foaming temperature>foaming water temperature; its viscosity reduction effect is optimal, when the foaming temperature is 150 ℃, water consumption is 3% and the temperature of water is 20 ℃. The influence degree of viscosity reduction of SBS modified asphalt is foaming temperature>water consumption>foaming water temperature; its viscosity reduction effect is optimal, when the foaming temperature is 160 ℃, water consumption is 3% and the water temperature is 60 ℃.
