Ground Paving using Coir Geotextiles in Roads

coir geotextiles in roads

Coconut coir geotextiles in roads are made by shredding the coconut with a shredding machine to produce a small piece of coconut. The coir fiber is then twisted into a coir rope using a spinning device. The diameter of the coir rope can be adjusted as needed. After the rope is formed, coir ropes are woven to resemble a net. The thickness of these diameters of rope can be adjusted as needed.

The material used to make coconut geotextiles is cheap and easy to find. Engineering uses coconut fiber geotextile as a pad or inner layer for the road. It can protect from water runoff and strengthen embankments, filtration and drainage.

Coir geotextiles or coir nets are spread directly on the surface used as roads. First, the ground is roughly leveled, and then a coir net is stretched over it. Coir geotextiles are an alternative solution for road surfacing because they are made from natural materials. The material is strong but can be degraded by soil. It is safe for the soil’s own ecosystem. It resembled a mixture of lime, cement, etc.

Coconut geotextile improves soil nutrients and is used after it decomposes. It becomes a nutrient and is advantageous for plant growth. Road application of coir geotextiles has been successful in areas with high compressibility and sloping soils. It is also used for road embankments and areas prone to abrasion and erosion.

Application of Coir Geotextiles in Road Surfacing

Roads laid on BC soil foundations develop ripples in the road surface due to loss of subgrade strength from softening during the monsoon. BC soil is a high clay content soil and a problem for road engineers. When dry, it shrinks and becomes so hard that the clods cannot be readily pulverized for road construction treatment. However, when it gets wet in the rain, it swells, loses strength, and poses a serious problem regarding subsequent road performance.

All these results crack on roads, so road engineers do not prefer to build roads. However, BC soil has no option, as black cotton soil is available in about one-third of the country. It is often impossible to construct a stable base course on a soft subgrade without losing expensive subgrade material that will infiltrate the soft subgrade; therefore, a soil amendment process must be used.

Coir geotextiles form one of the largest geosynthetic product groups. One of the most popular applications of geotextiles is the construction of sidewalks and embankments in soft soils. They are materials in the traditional sense, consisting mainly of synthetic fibers. However, natural fibers are also used in their manufacture.
