中文摘要:
      为研究水泥对砾石骨料与沥青胶浆粘附性的影响,将砾石骨料与碱性骨料经岩相鉴定后分组,分别通过水煮法与光电比色法试验测定骨料与不同沥青胶浆的粘附性。结果表明,水泥可有效改善骨料界面的化学性质,经水泥处理后的砾石骨料与沥青粘附性提高了14.6%,而经碱性石粉处理后砾石骨料与沥青粘附性仅提高了0.2%;水泥可有效改善胶浆的结构,砾石骨料与水泥沥青胶浆的粘附性比石粉沥青胶浆高27.0%,砾石骨料与水泥沥青胶浆的粘附性比碱性骨料与石粉沥青胶浆高18.3%,表明水泥可明显改善砾石骨料与沥青胶浆的粘附性。
英文摘要:
      In order to study the influence of cement on the adhesion of gravel aggregate and asphalt mortar, the gravel aggregate and alkaline aggregate were identified by petrographic identification and grouped. And then the adhesion between aggregates and different asphalt mucilages was determined by boiling and photoelectric colorimetry. The results show that the cement can effectively improve the chemical properties of aggregate interface. After cement treatment, the gravel aggregate and asphalt adhesion increased by 14.6%, while the gravel aggregate and asphalt adhesion only increased by 0.2%, which treated by alkaline stone powder; The cement can effectively improve the structure of mortar. The adhesion between gravel aggregate and cement asphalt mortar is 27.0% higher than stone powder asphalt mortar. The adhesion between gravel aggregate and cement asphalt mortar is 18.3% higher than that between alkaline aggregate and stone powder asphalt mortar, which indicates that cement can significantly improve the adhesion between gravel aggregate and asphalt mortar.
