Analysis of Fillers to Assess the Hot Mix Asphalt Performance: Sugar Cane Bagasse

Abstract

Transportation plays an important role in the development of a country. Due to the increase in the population, the demand for good transportation and passengers increased. For this purpose, new highways are built up every year. The demand for material for the construction is increasing and the researchers are in the race to find out materials which not only used as a replacer but also increase the strength parameters and decrease destresses in Hot Mix Asphalt pavement. In the present study Sugarcane, Bagasse Ash which is an agricultural waste was used as a filler material. At Optimum Binder Content 4.55 maximum stability of 7.03 KN was achieved while for the samples having stone dust as a filler material give maximum stability at 4.33 percent of 7.37 KN. Bagasse ash used as a filler in Wheel tracker test has given the best result at temperature 30⁰C and the average rut depth was recorded as 2.065mm while stone dust samples showed average rut depth 2.235mm at 30 ⁰Cand the number of passes was recorded as 14000. On the other hand, the samples which are subjected to a temperature of 60⁰C BA samples showed greater rut of the average value of 6.81mm whereas the average value of stone dust samples showed 6.615mm rut depth. From the above results, the author concluded that bagasse is the best modifier material for the areas having low temperature such as 30 ⁰C or below.
