GB/T 328.22 - 2007 focuses on the shear performance test of asphalt waterproofing membrane joints. It specifies the required equipment, such as the device that can apply shear force and its accuracy requirements. Prepare the sample, covering details such as the production method and size of the joint. During the test, the operating specifications such as shear rate and loading direction are clarified, and the judgment rules for the shear performance results of the joint are also given. According to this standard, the ability of asphalt waterproofing membrane joints to resist shear can be accurately evaluated, providing a key reference for membrane mass control and waterproofing engineering construction. It plays an important role in waterproofing membrane production and building waterproofing construction.
