摘要
为了改善植物沥青的抗水损害性能,文中通过黏附性试验、浸水马歇尔试验、冻融劈裂试验,研究了抗剥落措施改善效果和最佳掺量。结果证明在采取抗剥落措施后,植物沥青与基质沥青最大掺入比为1∶9时能够满足各项要求。胺类抗剥落剂效果不明显,消石灰改善效果最佳且最佳掺量为1%。
In order to improve the anti-water damage property of plant asphalt,the effect of antistripping agent and optimum addition quality are studied by using adhesion test,immersion Marshall test and freeze thaw split test in this paper.The result shows that the maximum mixing ratio of plant asphalt and base asphalt can meet the requirements of 1：9after adding anti-stripping agent.The effect of aminebased anti-stripping agent is not obvious,but the improvement of slaked lime is the best and the optimum adding volume is 1%.
