Road Paving Using Coconut Coir Geotextiles in Roads

coir geotextiles in roads

Coir geotextiles in roads – Soil has been used throughout the world as a construction material for buildings, roads, irrigation structures, etc. Due to the fragility of its tensile and shear strength, it is necessary to improve the soil according to the needs of the work, which vary from place to place. Soil stabilization has been done for centuries to improve the engineering properties of soil. The main method of stabilization includes mixing the soil with the highest strength soil or binding materials such as limestone/cement/calcium or reinforcement with suitable elements/fibre.

Roads laid on BC soil bases develop undulations on the road surface due to loss of subgrade strength due to subsidence during monsoon. BC soil is a very clayey soil and is a problem for road engineers. In a dry state, it shrinks and becomes so hard that the tows cannot be easily pulverized for treatment for use in road construction. When wet in the rain, however, it swells, loses strength and creates a serious road performance problem later on. Crack all these fruits on the streets, so better road engineers to build roads. In BC soil, but there is no choice as black cotton soil is available in about one third of the country. It is often impossible to build a stable base course over a soft subgrade without losing expensive base material that goes into the soft subgrade soil; therefore, a soil improvement method must be used.

Coconut geotextiles are one of the largest groups of geosynthetic products. One of the most common applications of geotextiles is the construction of paths and embankments in soft soils. They are materials in the traditional sense, consisting mostly of manufactured fibers. However, natural fibers are also used for manufacturing.

Application of Coconut Coir Geotextiles in Road Paving

Coconut coir geotextiles are produced by crushing the coconut with a shredder machine to create a small piece of coconut. The coconut fiber is then spun with a spinning device to make coconut rope. The diameter of the coconut rope can be adjusted as needed. After forming the rope, coconut ropes are woven to resemble a net. The thickness of this net can be adjusted as needed.

The material to make geotextiles from coconut is cheap and easy to find. Geotextile engineering uses coir fibers as an overlay or inner layer for the road. It can protect against the flow of runoff water and strengthen embankment, filtration and drainage.

Coconut geotextiles or coconut nets are spread directly over the area to be used as roads. First, the ground is roughly leveled, and then coconut netting is spread over it. Coconut geotextiles are another solution for road paving as they are made from natural materials. The material is strong but can be degraded by soil. It is safe for the soil ecosystem itself. It is compared to a mixture of lime, cement, etc.

Improving soil nutrients uses coconut geotextiles after it decomposes. It is nutritious and beneficial for plant growth. The application of coir geotextiles to roads in areas of high compression and sloping soils has been successful. It is also used for road embankments and land at risk of erosion and erosion.
