Quarry Dust – A Key Player in Improving The Geo-Technical Properties of Subgrade Soil
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 1
Abstract
:Quarries and aggregate crushers are basic requisites for construction industry and quarry dust is a byproduct of rubble crusher units. Disposal of such wastes poses lots of geo environmental problems such as landfill disposal problems and environmental hazards. Geotechnical and mineralogical characterization of quarry dust and its interaction behavior with soils can lead to viable solutions for its large-scale utilization and disposal Utilization of Quarry Dust. Improvement in engineering properties of soil such as an increase the CBR value reduces permeability, increase the compressive strength and increase the shear strength. Stabilization of the Sub grade Soil by Adding Quarry Dust increases the durability of pavement subgrade and avoid pot holes in highway which is one of major failure as it reduces the plasticity soil and it also benefits the design cost of construction.Shear strength and compressive strength of the soil for various mix proportions of quarry dust have been determined and compared in this project. It has also been concluded with the right percentage of quarry dust to be added to the soil to get the best stabilization.
