| 摘 要： | 针对环境因素和荷载对防水粘结层耐久性的影响，作者进行了水泥混凝土桥面防水粘结层现场测试试验。试验表明，由于桥面行车道和路肩上试块破损方式不同，路肩上抗剪强度大于行车道的，而路肩上拉拔强度小于行车道的。最后，提出从三个方面提高防水粘结层耐久性，即防水粘结材料的选择、铺装结构设计和改善施工过程。水泥混凝土桥面防水粘结层耐久性现场试验研究可为实际工程中防水粘结层的选材和施工提供依据。

| Abstract: | In order to measure the influence of the environment and load ingredients on the waterproof cohesive layer, some field tests for the layer on the concrete bridge deck were carried out. As a result of the tests, it is concluded that the failure modes of the travelinglane and the road shoulder were different, and the shear strength on the road shoulder was higher than that on the traveling lane, but the tensile strength on the road shoulder was less than that on the traveling lane. Finally, three measures wer... |
