摘要
纳米层状硅酸盐蒙脱土改性沥青是一种通过掺入纳米层状硅酸盐-蒙脱土以改善沥青胶浆以及沥青混合料的综合性能,从而提高沥青路面使用品质的复合材料,其突出特点是能阻止沥青材料的老化、减少车辙流动变形和疲劳破坏的出现,对于延长沥青路面的使用寿命具有显著作用。通过动态剪切流变仪(DSR)的温度扫描试验对纳米蒙脱土改性沥青胶浆的老化性能进行了流变学的分析。
Nano-montmorillonite modified bitumen is a kind of composition which has better properties for bitumen or mixture and improves the performances of asphalt pavement. The prominent character is resistance to aging, less occurrnace of rutting deformation and fatigue breakage. It has prominent effect to prolong the life of asphalt pavement. In this paper, the aging properties of nano-montmorillonite modified bitumen were studied through temperature sweep in DSR by rheological analysis.
