1. It is laid between the foundation and the base to drain the accumulated water between the foundation and the base, block the capillary water and effectively combine it into the edge drainage system. The structure automatically shortens the drainage path of the foundation, greatly shortens the drainage time, and can reduce the number of selected foundation materials used (materials with more fine materials and lower permeability can be used). It can prolong the service life of roads. 2. Laying a drainage net on the bottom can prevent the foundation fine material from entering the foundation layer (that is, it plays an isolation role). The aggregate base will enter the upper part of the geotechnical network to a limited extent. In this way, the composite geotechnical drainage network also has a potential effect of restricting the lateral movement of the aggregate base layer. In this way, its function is similar to the reinforcement effect of geogrid. Generally speaking, the tensile strength and rigidity of composite geotechnical drainage nets are superior to many geogrid used for foundation reinforcement, and this limiting effect will improve the supporting capacity of the foundation. 3. After the road ages and cracks form, most of the rain will enter the section. In this case, the drainage net is laid directly under the road surface in place of the drainable foundation. Drains allow moisture to be collected before it enters the ground/subfloor. A layer of film can also be wrapped on the bottom of the drainage net to further prevent moisture from entering the foundation. For rigid road systems, this structure allows roads to be designed with a high drainage coefficient of Cd. Another advantage of this structure is that it may allow concrete to hydrate more evenly (research on the extent of this advantage is ongoing). Whether it is a rigid road or a flexible road system, this structure can prolong the service life of the road. 4. In northern climatic conditions, laying drainage nets can help mitigate the effects of freezing and swelling. If the freezing depth is deep, the geotextile can be laid in a shallow position in the foundation as a capillary blockage. In addition, it is often necessary to replace a granular bottom layer that is not easy to freeze and expand to the depth of freezing. Freeze and swell backfill soil can be directly filled in the drainage net up to the ground line of the foundation. In this case, the system can be connected to a drain outlet so that the groundwater table is at a depth equal to or below this. This can potentially limit the development of ice crystals, and there is no need to limit traffic loads when ice melts in spring in cold regions.
