Detailed Analysis of Marginal Soil Stabilization with Fly-Ash and Its Admixture for Design of Flexible Pavements Using Shearing Strength and Liquefaction

Abstract

Transportation is an important component that shapes urban development. The current infrastructure in India, which consists of motorways, highways, and rural roads in almost 40 years old. As a result, there is a dire need for improvement or replacement or new construction due to wear and tear or by weathering action, insufficient capacity and sometimes not meeting current safety and design standards. The pavement involves the interplay of various factors such as wheel loads, traffic intensity, and a class of traffic. The pavements made by using non-modified soil are less stabilized and less durable. Different stabilization techniques are used to tackle this problem. The commonly available soil is mixed with the waste produced in the thermal power plant in the form of Fly ash and therefore the admixture soil characteristics were improved.
