摘　　要：介绍了弹性体改性沥青防水卷材接缝剥离强度的定义和试验方法,分析总结了影响接缝剥离强度试验结果的因素。针对GB/T 328.20—2007《建筑防水卷材试验方法第20部分:沥青防水卷材接缝剥离性能》提出了修订建议:认为“应按要求的相同粘结方法制备搭接试片”这一规定应补充完善,提出采用火焰法时应控制火焰大小适度,并采用规定的压辊滚压。The paper introduces the definition and test method of the peel strength of elastomer modified bitumen waterproofing membrane joint,and the factors affecting the test results of joint peel strength are analyzed and summarized as well.As for standard GB/T 328.20—2007“Test methods for building sheets for waterproofing——Part 20:Bitumen sheets for waterproofing-resistance to peeling of joints”,this article puts forward revision suggestions:it is considered that the provision“overlap test pieces shall be prepared with the same bonding method as required”should be supplemented.It also proposes that when using flame method,the flame size should be controlled appropriately and rolled with specified roller.

关 键 词：弹性体改性沥青防水卷材 接缝剥离强度 火焰法 压辊滚压
