Preparatory work. First, clean and level the roadbed to remove surface debris and unstable soil layers. Then, a layer of sand of the appropriate thickness is laid over the area to be reinforced to increase the uniformity and support of the base.
Laying geotextiles. Lay polyester filament nonwoven geotextile fabric on the surface of the roadbed, unfold them and fix them on the roadbed. The selection of geotextiles should be determined according to the actual situation, including the selection of appropriate specifications, tensile strength and pore size and other parameters. Construction personnel need to ensure that the geotextile is neat and straight to avoid wrinkles and overlaps.
Fixing and connection. The nonwoven geotextile fabric needs to be fixed on the roadbed with nails or other fixtures to ensure that it fits tightly and is firmly fixed. If it is necessary to cover a large area of roadbed, multiple geotextiles can be connected to achieve seamless connection to improve the overall reinforcement effect.
Soil covering and compaction. Cover a layer of sand or other suitable fillers with an appropriate thickness on top of the geotextile, and then carry out compaction treatment. This can increase the bearing capacity of the subgrade and prevent the geotextile from being exposed and damaged by the external environment.
BPM nonwoven nonwoven geotextile fabric are made by extrusion of fibers, which are entangled by needling and produce a dimensionally stable product. These nonwoven geotextiles are often best suited for a variety of geotechnical applications including drainage, filtration, protection and separation.
By using polyester filament nonwoven geotextile fabric for roadbed reinforcement, the stability and bearing capacity of the roadbed can be effectively improved, the risk of roadbed settlement and damage can be reduced, and the service life of the road can be extended. In addition, geotextiles can also provide certain waterproof and anti-penetration functions, reducing the impact of hydrological problems on the roadbed. This provides an important guarantee for the safety and reliability of road traffic.
