Analysis of results on bituminous mixes using natural fibers

Author Name : Anuj Narwal

In the present study, an effort has been created to review the consequences of use of a naturally and locally obtainable fiber known as SISAL fiber is employed as stabilizer in SMA and as an additive in BC. For preparation of the mixes aggregate gradation has been taken as per MORTH specification, binder content has been varied often from 4% to 7% and fiber content varied from 0.33 to maximum 0.5% of total mix. As a section of preliminary study, fly ash has been found to result satisfactory Marshall Properties and thus has been used for mixes in resultant works. Using Marshall Procedure Optimum Fiber Content (OFC) for each BC and SMA mixes was found to be 0.3%. Similarly Optimum Binder Content (OBC) for BC and SMA were found to be 5-hitter and 5.2% severally.
