| 摘要: |
| 采用黏附性试验分析了花岗岩与沥青的黏附性,据此确定了普通沥青和改性沥青添加抗剥落剂的最佳剂量;基于级配型抗滑沥青混凝土的设计理论,采用马歇尔体积设计法对花岗岩SMA混合料进行了目标配合比设计;参考所在地区(辽宁省)的技术指导经验,根据设计空隙率确定了花岗岩SMA混合料的最佳油石比;性能检验表明,花岗岩SMA混合料的各项性能指标均满足施工技术规范要求,特别是水稳定性能良好;经过2年试验路段的路面跟踪检测发现,试验路段的路用性能良好. |

| Abstract: |
| Adhesive test was used to investigate adhesive between granite and asphalt,and the optimum anti-stripping agent dosage is found.Based on the design theory of graded anti-skidding asphalt concrete,Marshall volume design procedure was applied to establish target gradation design of granite SMA mixture.The optimum ratio of asphalt to aggregate is determined from the volume of air voids and the technical guide of Liaoning province,China,and furthermore the mixture design was confirmed.The test results show that... |
