Performance Evaluation of Stone Mastic Asphalt Incorporating Sugarcane Bagasse Ash
Stone mastic asphalt (SMA) is a gap-graded asphalt mix consisting of high coarse aggregate content and rich mastic (asphalt and filler) content. The stone to stone contact between coarse aggregates results in higher rut resistance compared to other asphalt concrete mixtures. The rich mastic in the SMA Mix leads to increased durability and higher resistance to moisture damage. Due to higher asphalt content and stabilizing additive used in the production of SMA Mix leads to an increase in production cost which is one of the major disadvantages. This research evaluated the performance characteristics of SMA incorporating sugarcane bagasse ash (SBA) as a filler material and to study the cost-effectiveness. Four mixtures with different proportions of SBA used to assess the performance of the SMA. Mix 1 consisted of 2.5% SBA, Mix 2 consisted of 5% SBA, Mix 3 comprised of 7.5% SBA and Mix 4 consisted of 10% SBA by total weight of the mix. The resistance to moisture damage of Mix 1 and Mix 2 was within the allowable limit, and indirect tensile strength of Mix 1 and Mix 2 was higher compared to conventional mixes. Decreased draindown of bitumen for SMA mixtures without fibres containing SBA was observed. The results obtained show that the mix containing up to 5% SBA exhibited superior performance when compared to conventional mixes.
