摘　　要：采用正交试验法,考察了助乳化剂种类、稳定剂用量、增稠剂种类及用量四个因素在三种不同水平下对恩格拉黏度和储存稳定性的影响。极差分析表明:助乳化剂种类和增稠剂种类对乳化沥青的恩格拉黏度和储存稳定性影响较大。在均值分析显示的最佳试验条件下,制得了完全符合SHL/T 0099.5—2005标准的乳化沥青。The storage stability of emulsified asphalt was studied by orthogonal method including four factors on three different levels：the type of co - emulsifier,the stabilizer dosage,the type and dosage of thickener. The range analysis showed the type of co - emulsifier and thickener were the key factors of influencing the Engler viscosity and storage stability of emulsified asphalt.The emulsified asphalt was prepared at the optimum conditions which deduced by mean analysis fully met the standard SH / T 0099.5 - 2005.
