When the geotextile is directly laid on the surface of the roadbed or the road groove, the protrusions that may damage the fabric on the roadbed surface and the road groove must be removed first.
Common reinforcement materials: geogrids, geotextiles and georeinforced tapes, etc.
There are two main types of reinforcement in highway engineering:
①The stability of the embankment is insufficient. In order to improve the stability of the embankment and control the settlement of the embankment, geosynthetics are used for embankment reinforcement;
②In order to reduce the uneven settlement between the subgrade and the structure, the subgrade on the back of the platform is reinforced with geosynthetics.
Geosynthetic reinforced soil technology is a new geotechnical technology, but it has developed rapidly. Due to its reasonable structure, good stress conditions, simple construction and significant benefits, it is widely used in various filling projects. It uses synthetic polymers, such as plastics, chemical fibers, synthetic rubber, etc., as raw materials to make various types of products, which are placed inside the soil, on the surface or between layers of soil to strengthen or protect the soil.
One of the most rapidly growing applications of textiles is the use of geotextile. Geotextiles include for ground stabilization, geotextiles for water and soil erosion, geotextiles for roads, and geotextiles for moisture-proof.
High Strength Woven geotextiles are made of high-strength industrial synthetic fibers as raw materials and produced by weaving processes. The specifications are 35-250kn/m. Single-layer woven geotextile is also called geotextile. It has the same structure as general woven fabrics. Most geotextile fabrics are plain weave.
PP Mono Filament Woven fabrics Geotextiles ( GeofanTex® WN ) are produced either from tape (tape-fabrics) or yarns. Fabric consists of warp yarns and weft yarns. Woven fabrics are made of polypropylene monofilament and tape yarns that provide excellent hydraulic and physical properties
