A Review Study: Utilization of Coir Reinforcement for Unpaved Roads

Abstract

Abstract In this article, we discuss the founding of different research paper published so far using Coir across the globe in road construction. Coir is widely being used for a period of time in construction of pavements as a soil reinforcer. It is environment-friendly, biodegradable and sustainable hence does not poses any problem of disposal. The present study predominantly focuses on the utilization of coir improving the strength properties of lime balanced out sub-grade soil and then its cost benefits in designing flexible pavement for rural roads. Soil sub-grade is a key component of pavement, as they have to finally bear the burden coming over the pavement. Taking everything into account, the soil sub-grade should not be overemphasized at whatever point. The construction of streets in a large portion of the spots across the country is confronted with serious issues because of weak sub-grade soil. This Chapter includes the critical studies on the use of lime, coir and other filaments in the development of soil subgrade. The behaviour of fibre-reinforced soil and how it meets the need for lime addition and other industrial wastes has also been studied. In this article, we discuss
