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.
Geogrid is a major geosynthetic material. Compared with other geosynthetics, it has unique performance and efficacy. Geogrids are often used as reinforcements for reinforced soil structures or composites. Geogrids are divided into two types: polyester/glass fiber geogrid and plastic geogrid.
The polymer is in a directional linear state and forms a long elliptical network integral structure with uniform distribution and high node strength. This kind of structure has quite high tensile strength and rigidity and provides the ideal force bearing and spreading interlocking system for the soil.
The outstanding advantage of uniaxial plastic geogrid is that it has little tendency to deform (creep) under long-term continuous load, and its creep resistance is much better than geogrids of other materials, which play an important role in improving the service life of the project.
The interlocking action between the grid mesh and the soil constitutes an efficient stress transmission mechanism so that the local load can quickly and effectively spread to a large area of the soil, thereby reducing the local damage stress and improving The purpose of the service life of the project.
