Bridge bearing test item
1, compressive modulus of elasticity: to detect the elastic size of the product design.
2, shear modulus of elasticity: to detect the level of deformation stress of the product (key project)
3, ultimate compressive strength: test product bearing capacity storage modulus (key items)
4, shear bond performance: detection of internal steel plate and rubber bonding of the existence of defects, (the key project)
5, anti shear aging performance: testing the product aging resistance, the current standard test standard is low, the significance is not.
6, allow the performance: the maximum amount of rotation angle of void does not appear to allow detection of beam rotation process.
7, the friction coefficient of PTFE sliding plate and stainless steel plate detection: in the maximum friction grease lubrication condition.
