利用MTS试验机对防水材料分别施加不同次数的弯拉应力,采用防水材料90°剥离仪测试防水材料与混凝土桥面间的粘结力,通过分析粘结力的衰减状况来研究防水材料的抗疲劳性能,并提出了改善桥面防水层才才料疲劳性能的几点建议。
The MTS testing machine was used to apply flexural-tensile stress to the waterproof material at different times. The waterproofing material was tested for the adhesion between the waterproof material and the concrete deck using a 90 ° peel tester. The resistance of the waterproof material was studied by analyzing the attenuation of the bond strength Fatigue performance, and put forward some suggestions to improve the fatigue performance of deck waterproofing layer.
