Coir geotextiles in roads – Soil has been used worldwide as a building material for buildings, roads, and irrigation systems. Because the tensile strength and shear strength are weak, the ground must be improved according to the construction requirements, and the specific conditions vary depending on the place. Soil stabilization has been carried out over the past centuries to improve the engineering properties of soils. The main methods of stabilization include mixing the soil with a higher strength soil or reinforcing it with a binding material such as limestone/cement/calcium or suitable elements/fibers.
Roads laid on soil foundations in BC will undulate due to the loss of strength of the roadbed due to softening during the monsoon season. BC soils are high-viscosity soils that present a problem for highway engineers. When dry, it shrinks and becomes so hard that clods of earth are not easily broken up for road construction. However, when it gets wet, it swells and loses strength, causing serious problems in subsequent road performance.
All of this causes cracks in the roads, so road engineers don’t like to build roads in British Columbia soil, but since black cotton soil exists on about a third of the country’s land, they have no choice. Since it is often impossible to build a stable foundation on a soft subgrade without the loss of expensive parent material that penetrates the soft subgrade, ground improvement methods must be used.
Application of Coconut Shell Geotextile in Road Pavement
Geotextiles are one of the largest categories of geotextiles. One of the most popular applications of geotextiles is the construction of sidewalks and embankments in soft soils. They are fabrics in the traditional sense that are mainly composed of synthetic fibres, but manufactured using natural fibres.
The production of coconut husk geotextile is to crush the coconut husk into small pieces of coconut husk with a shredder. It is screened using a coconut husk screening machine to produce isolated coir fibers. The coir fibers are formed and twisted using a spinning machine to produce coir rope. The diameter of the cocoa rope can be adjusted according to your needs. Once the rope is formed, the coir rope is woven into the mesh. The density of the net can be adjusted according to your needs.
The materials from which coir geotextiles are made are inexpensive, easy to find, easy to apply, and biodegradable. Geotechnical or pavement uses palm fiber geotextile as an overlay or inner layer. Prevents runoff flow, strengthens dikes, filters and drains water.
Coir Geotextiles in Roads from Natural Resources Coconut Fiber
Coconut coir geotextiles or palm fiber mesh is laid directly over the area to be used as a road. First, the ground is roughly leveled, then the coir mesh is laid. Coir geotextiles are an alternative solution for paving because they are made from natural materials. The material is strong but deteriorated by soil. It is safe for the soil ecosystem itself. It has been likened to a mixture of lime, cement, etc.
Use palm geotextiles to improve soil nutrients after decomposition. It becomes a nutrient and is useful for plant growth. Coir geotextiles have been successfully used in road applications in highly compressible, sloping soils, embankments, and soils at risk of abrasion and erosion.
