A Brief Study on Industrial Waste used in Bituminous Mixes

Highway construction involves huge investment. A precise engineering design may save considerable investment, as well as reliable performance of the in-service highway can be achieved. Two major consideration are taken – pavement design and the mix design. This study emphasizes on the mix design considerations. A good bituminous mix design is result in a mix which is adequately strong, durable and resistive to fatigue and permanent deformation and environment friendly and economical. Due to the problems related to excessive waste generation, the need of recycling and reusing of waste material is arising for achieving the sustainability in construction activities. The present study focuses on the utilization of industrial waste as a filler material in flexible pavement. Fillers are very important in engineering properties of bituminous paving mixes. An attempt has been made in this investigation to assess the influence of mineral fillers such as ceramic dust, stone dust, crumb rubber and marble dust in bitumen paving mixes. The fillers used in this study are likely to solve partially the solid waste disposal of the environment. Four types of fillers was taken from different industries i.e. Ceramic Dust (CD) from ceramic industry, Crumb Rubber (CR) from automobile industry, Marble Dust (MD) from marble industry and Stone Dust (SD) from stone crusher. To check the suitability of these industrial wastes as filler in bituminous concrete, Marshall Specimens were prepared by adding filler in different doses i.e. 2%, 5% and 8%.
