Road infrastructures are pivotal to the development of infrastructure, transport and overall economy of any country which has a detrimental effect on the environment. So, adopting an eco-friendly pavement technology with the utilization of waste is of paramount importance. In this study, Cold mix asphalt (CMA) is produced with fillers like Fly ash (FA) and Rice husk ash (RHA) and parameters like Marshall stability, Marshall quotient, Indirect tensile strength, moisture susceptibility and rutting resistance of CMA mixes were determined through laboratory tests. Replacing SD with RHA and FA can improve the Marshall stability to 20.32% and 25.99% respectively. The Marshall quotient value of mixes with SD, RHA and FA are 1.93 kN/mm, 2.68 kN/mm and 3.01 kN/mm at 8%, 9% and 8% optimum binder content respectively. The betterment in tensile strength and moisture susceptibility of mixes was also found. The rutting deformation of the mix with SD is 16.57 mm, the highest among other filler mixes and the resistance has increased to 1.66 % and 52.16% after the application of RHA and FA filler. Finally, a detailed cost analysis was carried out and came upon that the mix with FA is the most cost-effective mixture.
