The high-strength spun geotextile produced by Yuanpeng Environmental Protection is woven from high-strength PET polyester filament, which has the advantages of high tensile strength, structural stability, good water permeability, and excellent creep resistance. It also has functions such as reinforced isolation and protection. In airport runway construction, the stable settlement structure of the roadbed is a crucial factor in ensuring the safety of aircraft taxiing.

The use of long filament spun geotextile in the construction of runway subgrade can effectively prevent uneven settlement of runway subgrade, isolate the phenomenon of slurry overturning caused by groundwater rise, prevent pits caused by hollowing out, prevent surface cracking caused by reflective cracks, and mitigate the impact of sand pits and ditches, resulting in significant losses. A layer of high-strength spun geotextile should be laid in the middle and bottom of the cushion layer within a radius of 30m to improve the overall structure.
