摘　　要：为了研究温拌沥青技术中表面活性剂型温拌剂掺量对沥青性能的影响,选取70号沥青和SBS改性沥青进行不同温拌剂掺量下沥青常规性能和流变性能(零剪切黏度、温度敏感性和频率敏感性)测试分析。结果表明:温拌剂掺量的增加降低了2种沥青的抗车辙性能,改善了沥青的温度敏感性,恶化了沥青的频率敏感性。因此,在实际应用中,应根据使用目的合理选择温拌剂掺量。In order to study the effect of surfactant type warm mixing agent dosage on asphalt performance in warm mixing asphalt technology,70#asphalt and SBS modified asphalt were selected for testing and analysis of conventional and rheological properties(zero shear viscosity,temperature sensitivity,and frequency sensitivity)of asphalt under different warm mixing agent dosages.The results show that the increase in the amount of warm mixing agent reduces the anti-rutting performance of two types of asphalt,improves the temperature sensitivity of asphalt,and worsens the frequency sensitivity of asphalt.Therefore,in practical applications,the dosage of warm mixing agent should be reasonably selected based on the purpose of use.
