摘　　要：采用中燃油公司基质沥青进行阴离子乳化沥青的制备,并对固含量、乳化剂用量、稳定剂用量等多个因素进行试验研究。结果表明,随着固含量和乳化剂用量的增加,阴离子乳化沥青的标准黏度增加,常温储存稳定性变小。稳定剂的加入能够明显改善阴离子乳化沥青的常温储存稳定性,但标准黏度会有所增大。Anionic emulsified asphalt is prepared by matrix asphalt from Petrochina Fuel Oil Company,and several factors such as solid content,emulsifier amount and stabilizer amount are studied experimentally.The results show that with the increasing of solid content and emulsifier,the standard viscosity of anionic emulsified asphalt increasing,but storage stability decreases at room temperature.The addition of stabilizer can obviously improve the storage stability of anionic emulsified asphalt at room temperature,but standard viscosity will also increase.
