K Rohit Kumar 01 01 This work analyses the mechanical characteristics of coir fiber reinforced bituminous mixes which is abionatural product Various quantities of coir fiber were applied to determine its effect in stability flow Marshallproperties and moisture susceptibility Based on research the coir fiber enhances the tensile strength durability andresistance to deformation of the bituminous mix Workability is not compromised as performance is maximized by theideal composition of fibers This paper will illustrate how coir fiber can become an ecologically safe additive toenhance the mechanical characteristics of the bituminous pavements and aid in creating a sustainably constructedroad Copyright (c) Journal of Engineering Technology and Sciences.
