Experimental Investigation into Low Temperature Properties of Thin Epoxy Bridge Deck Overlay Materials
Pages: 178-181
Year: Issue:  5

Abstract: 采用三点弯曲断裂、疲劳试验,室内加速加载磨耗试验和温缩系数试验研究薄层环氧铺装材料的低温性能.试验结果表明在-10℃时其弯拉断裂应变大于4 000 μm/m.当加载的疲劳应变大于1 000 μm/m时,仍表现出很好的低温抗疲劳性能.加速加载磨耗次数达到6万次后表面构造浓度大于1 mm,温缩系数为5.88×10(-5)/℃,水泥混凝土板表面浮浆清除和糙面处理可有效地增加界面黏结强度,以抵抗低温收缩应...
