Strengthening a Pavement Layer by Using Fly Ash

Transportation plays an important role in any developing countries. Recently, different modes of transportation are used for traveling, carrying goods, exporting, and importing the goods by comparing with other modes of transportation roads play a key role. In this regard, special care and attention have to be maintained throughout the construction in order to withstand the maximum loads. Stabilization of soil with fly ash will increase the soil properties and by that subgrade and base course strength of the pavement structure will also increase, when compared to normal soil subgrade and base course layers. Test results have shown that the optimum content of fly ash mixed with soil has shown good results.
