(1) Reinforcement for backfilling of retaining walls, or panels for anchoring retaining walls. Build a wrapped retaining wall or abutment.
(2) Reinforce the flexible pavement, repair cracks on the road, and prevent reflection cracks on the pavement.
(3) Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and freezing damage of soils at low temperatures.
(4) The separation layer between the ballast and the roadbed, or the separation layer between the roadbed and the soft ground.
(5) The isolation layer between artificial fill, rockfill or material field and foundation, and the isolation between different frozen soil layers. Reverse filtration and reinforcement.
(6) The filter layer of the initial upstream dam face of the ash storage dam or tailings dam, and the filter layer of the drainage system in the backfill of the retaining wall.
(7) The filter layer around the drainage pipe or around the gravel drainage ditch.
