Utilization of Brick Dust as Replacement of Fine Aggregates in Bituminous Concrete

Abstract

- Waste is defined as material by-products of any kind that have no residual value from human or industrial activities. Elimination of brick dust landfills is a serious and important task that is being considered by many countries around the world. The reuse of brick dust for road construction is a sustainable solution to ecological problems. The reuse of brick dust reduces road construction and landfill costs. The purpose of this study was to examine the overall performance of a bituminous concrete mix in which brick dust replaced certain combinations of specific aggregates in different proportions. In this study, brick dust was used in proportions of 5%, 10%, and 15% as a substitute for natural sand. The optimum range of substitution was determined based on results obtained from Marshall Parameters. In general, studies have shown that the use of brick dust in bituminous Concrete mixes is acceptable.
