Soil stabilization is a process that improves soil properties through chemical and mechanical techniques. The goal is to enhance the stability of weak soils for engineering projects like roads and airfields. Binders such as cement and lime are used to strengthen soils and increase their load-bearing capacity, durability, and resistance to water damage and differential settlement. Soil stabilization creates a more uniform foundation that reduces the likelihood of unsafe sinking or erosion of the soil over time.

2. Introduction
To The Topic
Soil stabilization is a process that involves
the improvement of soil properties by
implementing chemical and mechanical
techniques.
The goal of soil stabilization is to maintain
or improve the stability of weak soils to
achieve engineering goals.
Soil stabilization is a cost-effective
solution for many construction projects
that are undertaken.

Binders such as cement and lime are
used to enhance stabilization in soils,
developing their engineering properties
and generating an improved construction
material.
Equipment Used

3. Improved Load-
Bearing Capacity
The load-bearing capacity refers to the capacity and capability of the
soil to withstand wear and tear and load without failure. The bearing
capacity of a shallow foundation is calculated by multiplying the
bearing capacity factors with the soil strength parameter and adding
the contributions from the tip and the shaft of the foundation
By stabilizing the soil, its strength and load-bearing capacity can be
enhanced. This is crucial for roads and airfields that must support
heavy traffic loads, including vehicles, aircraft, and their associated
equipment.

4. Unstable soil can be highly susceptible
to water damage, especially in areas
with high rainfall or poor drainage.
Problem Identified
Mitigation of Water
Damage
Stabilization techniques such as chemical additives or
geosynthetics help reduce the soil's permeability and
increase its resistance to water infiltration.
This minimizes the risk of water-
related issues like erosion, swelling,
and loss of soil strength
Application

5. Enhanced Durability
Soil stabilization methods increase the soil's
resistance to wear, erosion, and deformation.
Soil stabilization provides toughness to the soil
with an improved gradation of soil.

Soil Modification

6. Reduction of Differential
Settlement
Differential Settlement can result in
uneven surfaces, bumps, or depressions
that can be hazardous for vehicles or
aircraft operations.
A few of these techniques include reducing the moisture of soil, usage of polymer
stabilizers, and grouting which will provide a predictable degree of improvement
to the soil.
Soil stabilization techniques help
create a more uniform and stable
foundation, reducing the likelihood of
differential settlement and ensuring a
smooth and safe travel surface.
Differential settlement occurs when different
sections of a road or airfield experience varying
degrees of settlement.

7. Control of
Soil Erosion
Stabilization methods like geosynthetics or chemical
additives help control erosion by improving the
cohesion and stability of the soil, preventing its
displacement and decay by water or wind.
Soil stabilization reduces the environmental impact of
construction projects which is done by reducing the
amount of soil that needs to be removed and replaced.
