| 中文摘要: |
| 江苏省高速公路上面层以玄武岩为主，高速公路的迅猛发展及石料资源分布的不平衡导致局部玄武岩供应紧张，室内试验及试验路资料表明，在使用改性沥青并添加液体抗剥落剂后，石英砂岩、花岗岩、凝灰岩及安山岩与沥青粘附性能够满足江苏省高速公路技术标准的要求，沥青混合料具有良好的高温、低温性能，抗水损害能力，石英砂岩、花岗岩、凝灰岩及安山岩等石料可以应用于高速公路上面层。 |
| 英文摘要: |
| Basalt is often used in the pavement of Jiangsu province,while basalt is in short supply because of the development of pavement and the imbalance of stone resource distributing.Results of lab and field tests show that the adhesiveness between the quartzite,granite, tuff, andesite and bitumen can meet the requirement of Jiangsu expressway standard after the modified asphalt and liquid anti-stripping agent being used.The mixture shows excellent performance in high or low temperature and water damage resistance, so that the quartzite, granite, tuff and andesite can be used in the top surface. |
