Modern GROUND IMPROVEMENT TECHNIQUES FOR HIGHWAYS
INTRODUCTION
 Transportation contributes to the economic,industrial,social and cultural development of any country.
 Transportation by road or highways is the only mode which could give maximum service to one and all.
 When the soil on a project site cannot support the loads, ground improvement to increase strength, reduce compressibility, and enhance performance under applied loadings may be required.
 The field ....etc

GEOTEXTILES IN TRANSPORTATION APPLICATIONS

GEOTEXTILE
Geotextile is defined as a permeable textile material used in contact with soil, rock, earth etc as an integral part of civil engineering project, structure or system
It may be of natural materials such as jute,coir,cotton etc.
Or of synthetic polymers such as polypropylene, polyamide, polyester,polyethylene


FUNCTIONS OF GEOTEXTILES

1. SEPARATION
2. FILTERATION
3. DRAINAGE
4.REINFORCEMENT
5. SEALING FUNCTION

DESIGN PROPERTIES

1. PUNCTURE STREN ....etc

Textiles were first applied to roadways in the days of the Pharaohs Even they struggled with unstable soils which rutted or washed away They found that natural fibers, fabrics or vegeta-tion improved road quality when mixed with soils, particularly unstable soils Only recently, however, have textiles been used and evaluated for modern road construction This fact sheet clarifies the confusion over terms and definitions of geo textiles, and discusses their common roadway and erosion control applications

ABSTRACT:
Ground improvement techniques utilising Vibro methods, Deep Soil Mixing and Grouting
technologies are finding increasing application in Malaysia to solve a broad spectrum of geotechnical problems.
This paper will describe recent applications in Malaysia for four separate projects – Jet Grouting to form stable
cutter-head interventions for a tunnel project; Deep Soil Mixing to support deep vertical basement excavation with
limestone interface for a commercial complex; Vibro Concrete Columns to found reinforced concrete ....etc

GROUND IMPROVEMENT TECHNIQUES FOR HIGHWAYS

INTRODUCTION
Transportation - needed for the development of the country.
The main mode of transportation is by road or highways.
In the process of road development, the alignment of road may have to be fixed through the soils which may not bear the traffic loads .
There are various techniques of ground improvement.

METHODS FOR GROUND IMPROVEMENT
Soil stabilization
Vertical drains
Stabilization trenches
Capillary cut-off
Soil nailing
Stone columns
Vib ....etc

Introduction
General practice is to use shallow foundations for the foundation of structures if the soil close to the ground surface possesses sufficient bearing capacity. However, where the top soil is either loose or soft, the load from the superstructure has to be transferred to deeper firm strata. In such cases, pile or pier foundations are obvious choice.
There is also a third method which may in some cases prove more economical than ....etc
