D025 Waterproof coating (coiled material) seam deformation capacity fatigue testing machine
Test geotextile wide strip specimens and various rubber materials (waterstop materials), waterproof membranes, waterproof sealing materials, cables and other composite materials for dynamic fatigue tensile testing. Tensile, burst and tear performance tests. The joint and seam tensile of geotextile and geosynthetic fabric were measured with a wide sample. Road and bridge tunnel joint glue anti-fatigue test, road asphalt mixture and inorganic binder, concrete reflection crack test. This machine complies with: "Waterproof coating for road and bridge" JC/T 975-2005, 6.20; "Polyurethane waterproof coating" GB/T 19250-2013, 6.25
