Appraisal of Sustainability of Wooden Charcoal as Filler in Stone Matrix Asphalt

Abstract

The main objective of this study is to examine the possible use of solid wastes charcoal for improvement of pavement strength, the use of asphalt material and its combination are used so that their strength and performance can be improved. For which the suitable mixture that is been adopted is Stone mastic asphalt which is better than bituminous Concrete. For minimizing the cost and increasing the effectiveness of roads, many different option are used for improvement by using different waste materials as a fillers among them wooden charcoal is best option. The Stone Mix asphalt is gap-graded mixture Consisting of Stone as Coarse aggregate, different binders are used (natural or artificial) as a stabilizers and. In the research work, the main objective is to compare the outcome obtained by using fillers like Stone dust, Portland cement, Fly ash with wooden charcoal. The properties that charcoal possesses are resistance to crushing, absorption, surface grading, moisture resistance to freezing, light weight, heating and synthetic resin glues which is the majority important for pavement of roads. Therefore its solidity and flow parameters and Air Void ratio are obtained so that it may be compare with different types of Fillers, From that we can set up a perfect combination so that it can be useful as a replacement as a filler for improving the quality and durability of pavement. Therefore aggregate gradation is taken as per IRC-SP-79 specification for SMA. The Binder Content is varied as 4%, 5%, 5.5%, 6%, 7% by weight of aggregates. 0.3% by is used as Optimum Binder Content. Binder of 60/70 penetration grade bitumen is used. For experiment, Marshall Test method is used for obtaining better results.
