SOIL IMPROVEMENT WITH LIME

Abstract

Design of Pavement is based on the premise that minimum specified structural quality will be achieved for each layer of material in the pavement system. Each layer of road must resist shearing. It should avoid excessive deflections that cause fatigue cracking within the layer or in overlying layers, and prevent excessive permanent deformation through densification. As the quality of a soil layer is increased, the ability of that layer for load distribution over a greater area is generally increased so that a reduction in the required thickness of the soil and surface layers may be permitted. The most common improvements of different layers are achieved through stabilization include better soil gradation, reduction of plasticity index or swelling potential, and increases in durability and strength. In wet weather, stabilization may also be used for construction operations to provide a working platform. This study focuses on the subsequent construction aspects of treating soils with lime.
