| 摘 要： | 测定沥青与不同液体的接触角,利用Owen-Wendt法确定沥青的表面自由能,考察不同抗剥落剂及其与多聚磷酸的复配对沥青表面自由能的影响。结果表明:抗剥落剂的加入增加了沥青的表面自由能,提高了沥青-集料界面黏附能力,可增强沥青混合料的抗水损害能力;抗剥落剂与多聚磷酸的复配可降低沥青的表面自由能。 |
| 关 键 词： | 沥青 表面自由能 抗剥落剂 水损害 接触角 |

| Abstract: | The surface free energy of the asphalt binder was determined using the Owen-Wendt method by determining the contact angles between asphalt binders and different probe liquids.The effects of different anti-stripping agents and its complex with polyphosphoric acid on the surface free energy of asphalt binder were evaluated.The results indicate that the anti-stripping agents increase the surface free energy of asphalt binder and the adhesion ability between asphalt and aggregate,which enhances the moisture damage resistance of asphalt.The addition of anti-stripping agents with polyphosphoric acid can reduce the surface free energy of asphalt binder. |
| Keywords: | asphalt binder surface free energy anti-stripping agent moisture damage contact angle |
