Performance Evaluation of Bituminous Paving Mixes Containing Sisal Fiber as an Additive
Abstract Cellulose fibers are generally used as a stabilizer in bituminous mixes like stone matrix asphalt (SMA) mixes, to stop draindown of the binder from a mix, and are also helpful in reinforcing the cracked roadway. This present study investigates the potential use of naturally occurring fibers known as sisal fiber as a stabilizer in stone matrix asphalt as well as dense-graded bituminous mix namely bituminous concrete (BC). Marshall test is simple, economical, and commonly available to evaluate the optimum bitumen content (OBC) and optimum fiber content (OFC) of mixes and to predict various Marshall criteria: Marshall stability, flow value, air voids, voids in mineral aggregate, and voids filled with bitumen. In this study, VG 30 bitumen has been used as a binder and fly ash, a waste material which has been used as filler. Further, the paving mixes were investigated based on various laboratory tests such as draindown test, moisture susceptibility test, and dynamic modulus test where mixes are prepared at their respective OBC and OFC. The test results indicated that addition of 0.3% of sisal fiber to a mix with fly ash as filler remarkably improves the engineering properties of both mixes considered.
