| 摘 要： | 采用不同用量的北美岩沥青(G ilson ite)在高温条件下对石料进行预拌裹覆,然后再添加沥青和改性沥青拌制成沥青混合料,并对其各项路用性能进行了对比试验研究。试验结果表明,添加适量的北美岩沥青后沥青混合料的高温稳定性显著提高,低温性能也有所改善,抗水损害等各项性能指标良好。

| Abstract: | In this paper,Gilsonite modified asphalt mixtures are manufactured by various dosage of Gilsonite being added during the dry cycle of the mixing procedure onto the hot aggregate rocks before bitumen being added,and then the Gilsonite modified asphalt mixtures are researched on their road performance.Test results show that the high temperature stability of mixture after proper dosage of Gilsonite being added as modifier is markedly enhanced,the low temperature performance of the mixture is also improved,and its property of resistance to water induced damage is fine. |
