摘　　要：通过车辙试验.分析了掺入SEAM的AC-13沥青混合料高温抗车辙性能的影响因素,并运用灰关联熵分析法对SEAM掺量、沥青针入度、沥青当量软化点、沥青用量、4.75 mm筛孔通过率、沥青混合料空隙率等影响因素进行分析。研究表明,SEAM掺量、空隙率和沥青当量软化点对SEAM沥青混合料高温稳定性有重要影响。Based on the wheel rutting test, influencing factors on high temperature stability of AC 13 asphalt mixtures with different percent of SEAM were discussed. Besides, the grey correlation entropy method was applied to analyze different factors such as SEAM content, asphalt penetration, asphalt equivalent softening point, asphalt content, the percentage of 4.75 mm sized aggregate passing through the mesh, volume of air voids in asphalt mixtures. The results showed that SEAM content, volume of air voids and asphah equivalent softening point have a great effect on SEAM asphalt mixtures.
