| 摘 要： | 通过室内试验，研究了不同SBS改性剂掺量下，改性沥青技术性质及相应混合料性能变化规律。试验结果表明：SBS改性剂的添加，能有效改善基质沥青材料的高、低温性能，且随着改性剂掺量的变化，混合料性能呈现不同的变化规律。考虑到对路面整体路用性能的影响，确定了SBS改性剂的最佳掺量。

| Abstract: | Based on the indoor experiments, the material properties of modified asphalt and road perfor-mance of asphalt mixtures with various dosage of SBS modifier are studied. The data show that：by adding the SBS modifier, the high and low temperature performance of asphalt materials can be effectively im-proved, and different change rules of asphalt mixtures are presented as the dosage of SBS changes. Taking the overall road performance into account, the optimal dosage is ensured. |
