Study on Stabilization Option for Soil Subgrade in Low Volume Bituminous Pavements

Abstract

Life cycle cost analysis is a tool to determine total economic cost of a project segment by analysing initial cost and discounted maintenance cost. A productive maintenance work is the key for cost-beneficial and safe transportation. Yet,the maintenance work summed up from routine maintenance action per year to surface renewal and periodic renewal of the road network.KENPAVE is computer software,which helps in performing the response of pavement structure to traffic loading by computing stress and strain with in its layers and helps in the design of pavement. This study includes making a cost effective analysis and comparing that with two different design options to find out the best among them within the budget, before being done in field work.The objective of this project is to create a multiobjective pavement design model considering all necessary and sufficient factors responsible in maintenance activities of pavement so as to minimize the total cost. In this study, fly ash has been used for soil stabilisation of sub grade to facilitate the benefits of the stabilisation and to analyse the total cost of the project
