Geosynthetics

Introduction Geosynthetics has been widely used in geotechnical engineering and environmental engineering for the past four centuries, but it is used especially in the field of construction engineering, especially for the construction of limited or very expensive traditional building materials . Advances in the application of geosynthetics in reinforcement and environmental protection: geosynthetics commonly used for soil reinforcement include geotextiles, geogrids and geocells. Geotextiles are sheets of continuously woven, nonwoven, knitted or bonded fibers or threads.

Geosynthesis such as geotextiles, geogrids and geocells are often used in various pavement layers to improve road quality. These materials and methods are used not only for public roads and highways, but also for less trafficful roads. Geosynthetics plays four major functions on the road, separation, consolidation, filtration, drainage, which improves pavement performance, reduces construction costs, and reduces maintenance. The completed road is completed by laying or leaving gravel or other natural ground. The type of pavement depends on economic factors and purpose of use. Safety measures such as traffic signs, collision prevention, pavement signs, other types of pavement signs, etc. are given

This construction method combines geosynthetics reinforcement and granular soil, which are placed at narrow intervals, into a new composite. It builds an abutment and is used near the dam. This technique reduces the possibility of settling at the edge of the bridge and creating a ridge. Using the GRS-IBS makes it easier to build and maintain the bridge. Depending on the project, this method is cost effective from 25% to 60% more than conventional construction method. PBES is a structural element of a bridge built outside the site or close to the construction site. By constructing these parts in advance, compared with traditional construction methods, construction time of the bridge at the site can be drastically shortened. Utilities and engineers can plan and prepare components such as pipelines, cables, fasteners in advance, and install them quickly and efficiently on site.

In many cases, there are some restoration techniques with high soil stability in civil engineering practices such as geosynthetic reinforcement and soil nailing that are expensive to use on slopes, but now there are many restoration techniques in the world such as civil engineering Sustainable alternative means are being considered. Application to vegetation covering or soil biotechnology engineering This approach is an environmentally friendly approach that reduces cost and local labor. The impact of vegetation on soil slopes is generally divided into two categories, mechanical effects and hydrological effects. Hydrological effects are the main cause of soil moisture content, which increases the evapotranspiration, thereby increasing the soil matrix attraction. Water is removed from the soil in a number of ways, either by evaporation from the surface or by evaporation by vegetation covering. This process produces water flowing upward from the earth
