In road construction, after the pavement is completed, in order to prevent the road from being dry and cracked and causing damage to the road, water is usually continuously sprayed on the road to keep the road moist; if it is in the hot summer, the water will evaporate within a few minutes after spraying, causing water to be sprayed. The workload is very large. Geotextile plays an important role in road maintenance. Spreading geotextile flat on the road can effectively prevent the rapid evaporation of water!

The role of geotextile: isolation; using geotextile to isolate building materials of different properties, can make different types of materials not mixed, and maintain the structure and efficacy of the materials. Filtration; By using the good air permeability and water permeability of geotextile, it can effectively intercept the fine sand and small stones contained in the water, which can protect the stability of the water project. Drainage; Geotextile has good water conductivity, which can remove excess water and gas from the soil. Reinforced protection; geotextile can effectively prevent the soil from being damaged by external forces.
