A Comparative Study B/W Black Cotton Soil and Alluvial Soil for Economical Pavement Design by Lime & Fly-Ash Stabilization

As we know the road development is one of the major parts of growing infrastructure & Pune, which is expanding at a very fast rate, the construction of roads is of major concern. Fly Ash is one of the abundant forms of Solid Waste produced at thermal power plants. Its disposal is a big problem keeping both these concerns in mind it was tried to come out with a project which will integrate Road development and Fly ash disposal. Thus, in this project we intend to use Fly ash & Lime in roads which will help us in following manner:  High volumes of Fly ash will be used which will save the dumping sites to be used for better purposes.  The use of fly ash will reduce the consumption of high volumes of fertile soil that can be used for cultivation purposes.  Due to binding properties of lime & Fly ash, the pavement designed will be of higher strength.  Overall thickness of the pavement can be reduced. Two types of soils were used in this project, namely Alluvial Soil and Black Soil taken from nearby Pune.
