摘　　要：嵌缝板吸水率是考察混凝土接缝密封耐久性的一项重要指标,但是采用不同的试验方法、试验动作的不统一、处理后试件表面太干或水分残余过多等都会造成吸水率试验结果的不准确。本文研究了不同试验方法以及同一试验方法中不同的试验细节对吸水率结果的影响,并提出了适合国内标准体系的吸水率试验方法。Water absorption of sealing and caulking plate is an important indicator to investigate the durability of concrete joint. However, the use of different test methods, inconsistent test actions, too dry or excessive water retention of specimen surface can cause inaccuracies results of water absorption tests. This article studies influences of different test methods and different details in the same test method on results of water absorption, and proposes water absorption test method suitable fi）r the domestic standard system.
