Rice is the most important food crop produced in Asia. Throughout the world, 90 % of rice is produced. During the production of rice, many stable wastes like straw, husk, bran, and broken rice are generated. According to many investigations, the agricultural wastes may be used as substitute’s substances for the traditional bituminous mixes which can be cost-effective and sustainable alternative to the problem of the stubble burning. The usage of rice straw ash (RSA) as filler in the mix for evaluation of an environmentally friendly and economic point of view. Bituminous Mixes are most commonly used worldwide. The economic cost of aggregates and fillers is increasing day by day and there is lack of availability of natural material resources. To deal with this problem, here the study emphasizes an evaluation of the mechanical performance of bituminous using rice straw ash. This paper deals with the partial replacement of fine sand with different proportions of rice straw ash 3%, 5%, 7%, 9% respectively is employed at different bitumen content of 5, 5.5, 6, 6.5 and 7. In this laboratory Investigation Marshall Stability test is conducted on test samples considered as a design and evaluation of bituminous paving mixes. The Mechanical properties of this material will be checked to whether it is beneficial or not. RSA is a better option on low to medium traffic roads.The impact of RSA as filler material in the bituminous mix on waft and balance values is to be investigated. These studies targeted the Maximum Stability and Flow Value of the asphalt mixture with the waste. From the experimental research, it is concluded that the optimum bitumen content material is determined at 9% rice straw ash with 6.5 bitumen content. Bitumen properties also increase with the addition of rice straw ash.
