摘要
为改善抗水损害性能,通过浸水马歇尔稳定度试验及冻融劈裂试验,研究了AR-68抗剥落剂、水泥、消石灰在单掺或复掺时对沥青混合料抗水损害性能的影响。结果表明,以上几项措施都在一定程度上改善了沥青混合料的抗水损害性能,特别是AR-68抗剥落剂和水泥复掺时的改善效果最为明显。通过在兰州平凉路路面加层改造工程中的应用,证明AR-68沥青抗剥落剂在改善沥青路面抗水损害方面性能优异。
To improve water resistance,the influence of AR-68 anti-stripping agent,cement and lime,or their compound mix on water resistance of asphalt mixture are analyzed separately through Marshall Stability Test and freeze-thaw splitting test.The results show that the said measures have improved water resistance of asphalt mixture to a certain extent.Especially the compound mix of AR-68 anti-stripping agent and lime has the most significant effect.Through the application in pavement overlay engineering of Lanzhou Pingliang Highway,it is proven that AR-68 anti-stripping agent has excellent effect in improvement of water resistance of asphalt pavement.
