Abstract

Highway construction involves huge investment in men and material. There are many alternatives for improving the stability and efficiency of pavement structure. Asphalt material and mixture are used to improve the durability and performance of pavements. SMA requires stabilizing additives composed of cellulose fibres to prevent drain down of mix. SMA consists of 70-80% of coarse aggregates
that interlocks to form a skeleton structure which resists permanent deformation. The main objective of this work is to compare the volumetric properties of SMA at 5-7% of bitumen content by using fillers like stone dust, coconut shell charcoal, concrete dust and coir as a fibre which possesses resistance to crushing, surface moisture, resistance to freezing, light weight, adsorption, synthetic resin glues which is most important for pavement of roads. Therefore its volumetric properties like stability, flow and air voids ratio
which are obtained that are compared with properties of different types of fillers. From that we can establish a perfect combination of filler material for SMA, so that it can be useful as a substitute of filler in reducing cost, improving the quality and durability of pavement structure.
