"Break Elongation" has always been one of the most critical indicators for HDPE geomembranes, with both GB/T 17643-2025 and GRI-GM13 2016 requiring ≥700%. This indicator is directly related to whether HDPE geomembranes can withstand the deformation of the substrate caused by significant external forces under extreme long-term service conditions...

Railway engineering projects have long service lives and high subsequent maintenance costs. Among them, railway subgrade reinforcement works are situated in the middle stage of overall construction. If the reinforcement materials are damaged during acceptance or after being put into use, complete repair is required. However, the cost twill be difficult to estimate.
