| 摘 要： | 通过粘附性、马歇尔稳定度、残留稳定度等试验，讨论了SBS改性沥青耐海水及硫酸盐溶液侵蚀性能。结果表明，在海水和硫酸盐溶液的作用下，SBS改性沥青的水稳定性有一定下降。通过掺加短纤维增强的方法。可以减弱海水及硫酸盐溶液对混合料水稳定性的影响。

| Abstract: | The effect of water stability on SBS modified asphalt in seawater and aqueous sulphate is studied using the way of the cohesiveness, Marshall Stability and remnant stability. The result shows that seawater and aqueous sulphate can decrease the stability of SBS modified asphalt. Adding 0. 3 % polyacrylonitrile fiber into asphalt concrete can weaken the effect of seawater and improve the water stability. |
