不同矿料级配对抗车辙剂沥青混合料高温性能的影响
|
摘要
为探讨不同矿料级配对掺入抗车辙剂沥青混合料高温性能的影响,试验采用不同类型(AC-13辉绿岩、AC-16辉绿岩、AC-20石灰岩)的矿料级配,用动稳定度作为改性沥青混合料的评价指标,分别进行沥青混合料的室内试验研究。研究结果表明:同一试验条件下,矿料级配的差异性对抗车辙剂改性沥青混合料的高温性能影响很大,且辉绿岩的混合料高温性能优于石灰岩。
In order to investigate the effect of different mineral aggregate gradations on the high temperature performance of asphalt mixture mixed with anti-rutting agent, mineral aggregate gradations(AC-13 diabase, AC-16 diabase and AC-20 limestone) of different types were employed, the dynamic stability was used as the evaluation index and laboratory test of asphalt mixture was conducted respectively. The results showed that the difference of mineral aggregate gradation had significant influence on the high temperature performance of modified asphalt mixture under the same test conditions, and the high temperature performance of diabase was better than that of limestone.
