The geotechnical synthetic material comprehensive testing instrument is used for testing the mechanical properties of geotechnical synthetic materials and the characteristics of soil-fabric interaction. It can perform mechanical tests on the geotechnical material itself, such as strip tensile testing, grip tensile testing, tear testing, CBR puncture testing, and penetration testing; and also direct shear friction testing and pull-out testing for soil-fabric interaction.

Application

It is used to determine the bursting strength of geotextiles, geomembranes and geocomposite materials composed of geotextiles and geomembranes. The specimen is clamped on the elastic diaphragm, the liquid pressure is applied under the diaphragm to expand the diaphragm and the specimen, and the liquid volume is increased at a constant speed until the specimen is broken, and the bursting strength and bursting degree are measured at this time. In the absence of a sample, the burst strength of the expanded film is measured when it reaches the burst height with a sample, and the difference between the two is the burst strength of the sample.

FAQ

1. What is a Geosynthetics Bursting Strength Tester?

The Geosynthetics Bursting Strength Tester is a device used to measure the bursting strength of geosynthetics, such as geotextiles and geomembranes, by applying multi-directional stress until failure. This simulates real-world pressure conditions on the material.

2. How does the bursting strength test work?

The tester applies hydraulic or pneumatic pressure evenly across the surface of the geosynthetic sample. The pressure is gradually increased until the material ruptures, and the maximum pressure is recorded as the bursting strength.

3. What types of geosynthetics can be tested?

It can test woven, nonwoven, knitted geotextiles, geomembranes, geogrids, and composite geosynthetics used in civil engineering, drainage systems, embankments, roads, and landfill liners.

4. What parameters are measured during testing?

The tester measures maximum bursting pressure, deformation at failure, and rupture characteristics. Some models provide automated data logging and visual analysis of the failure point.

5. Why is bursting strength testing important?

Testing ensures geosynthetics can withstand multi-directional stresses in real-world applications, preventing tears or failures under high pressure. It helps engineers and manufacturers select materials with reliable strength and long-term durability.
