The effect of semi-rigid base layer conditioning period, high penetration emulsified asphalt spread temperature and conditioning temperature to the penetration effect were also analyzed. Furthermore, the shear strength test between surface and base layers were utilized to obtain the optimal content of high penetration emulsified asphalt.

并分析了基层养生龄期、高渗透乳化沥青洒布温度、养生温度等因素对渗透效果的影响。其次，进行了基层与面层间抗剪强度试验，得到了高渗透乳化沥青最佳用量。
