APPLICATIONS OF COCONUT SHELL AND COCONUT FIBRE IN FLEXIBLE PAVEMENTS: EXPERIMENTAL STUDY ON USAGE OF COCONUT SHELL AND COCONUT FIBRE IN FLEXIBLE PAVEMENTS

Flexible pavement systems play a crucial role in modern transportation infrastructure,demanding materials that enhance structural integrity and durability. This study explores the potential of utilizing coconut shell can improve the indirect tensile strength and static creep behaviour while coconut fibre can increase the stability, skid resistance and resilient modulus as a sustainable alternative in flexible pavement construction. However, concerns regarding environmental impact and sustainability have prompted the exploration of natural fibres. There search involves a comprehensive experimental investigation, focusing on the mechanical properties and performance of coconut fibre-reinforced flexible pavements. Various literatures has been evaluated and ultimately the coconut shell has been used for various purposes, such as lightweight concrete, landfill, structural concrete and also used in road construction. The test which we performed for flexible pavement includes los Angeles Abrasion, aggregate impact value and aggregate crushing test. This investigation gives the use of the coconut shell 10mm size replacing with 10mm size coarse aggregates.
