Experimental Evaluation of Rutting Resistance of Sugar Cane Bagasse Ash Modified Asphalt Mixture

Abstract

Abstract: Bagasse ash (BA) was used as filler in hot mix asphalt. Mineral fillers in asphalt concrete mixes have a significant influence on asphalt concrete performance. Although mineral filler is just a minor percentage of the total performance of asphalt concrete, it plays a critical function. Bagasse Ash (BA) was utilized as a filler ingredient to test and assess the performance of asphalt concrete. BA was used in variable ratios to replace Stone Dust (SD) in road construction. Filler was used in varying quantities (4%, 5.5%, and 6.5%). Furthermore, BA is used to replace the traditional SD filler in partial replacements of 10%, and 20%, as well as full replacement of SD. The Marshall Mix Design Method was used with three different amounts of bitumen, namely 4%, 4.3%, and 4.6%. By using National Highway Authority’s (NHA) general criteria for Optimum Binder Content, a total of 108 samples were produced. The prepared mixes showed good outcomes, and the majority of them passed the NHA's main requirements. Some of the mixtures do not meet the VMA and VFA requirements given in MS-2 Asphalt Institute 2014. Two forms of performance testing are the Dynamic Modulus Test and the Wheel Tracking. A total of twelve OBC samples are evaluated for wheel tracking and dynamic modulus. Bagasse Ash has been tested in the lab and found to be capable of being used as filler in both partial and full replacement of conventional stone dust filler.
