Economy Growth Rate in India at a Glance


Indian Economy Overview

GDP growth rates of the ‘BRIC’ pack

• India is one the largest and fastest growing economies in the world• Notwithstanding the economic slowdown, India continued to grow at 6% +• India's GDP is projected to grow @ 8-10% for the foreseeable future

In US$ Billion

Data source: IMF

Government of India in the Annual Budget 2010-2011 has ambitious plans for

the investment in infrastructure development:

Roads & Highways

• National Highways Development Projects at a glance (NHDP):NHDP envisages :

6-laning 6,500 km4-laning 17,500 km Upgrading of 20,000 km of National HighwaysInitiating development work of 1000 km of expressways.The MORTH has plans to build 20 Kms. of new road for the whole year.

The projected investment is about Rs. 8,12,661 Cr. ( USD 179 billion) over a period of six(6) years.


Potential for Geosynthetics in India

Assuming that even 30% of the road stretches use Geo- textiles, this itselfwill require 46 million sq meters i.e. 9500 tons in next 3-4 years.

Ports• National Maritime development projects (NMDP):

India has a 7500 Kms. of coastline Currently, 12 Major ports (6 each in West & East) & 45 Non major and private

ports are operational. To provide additional capacity and to upgrade the present infrastructure to

international standard, an investment of about Rs.50,000 Cr. (US$ 11 bn) is envisaged in the major ports during the next five(5) years.

Port trust will undertake :- Development of 54 new Berths in next 5 yrs.- Several dredging projects would be undertaken- Road & Rail connectivity projects of over Rs.7,000 Cr.(US$ 1.5 bn)

is under implementation

There is huge potential of use of Geotextiles in coastline as it is specifically used for a purpose of Scour protection.


Potential in India based on current budgets

Railways

Indian Railways is one of the largest railway system in the world

An Expansion of new 25,000 km length is proposed in next 10 yrs. Time

A dedicated freight corridor project estimated to cost about Rs.57,000 Cr.(US$12 bn) is being implementation.

Railways plan development of superfast trains ,350 kmph , for which use of Geotextiles will be a must

Geosynthetic can play a very vital role in improving the cost effective track structure design.



Airports

India is currently the 9th biggest aviation mkt. in the world.

About 10 major and 40 smaller airports exist

The passenger traffic is expected to cross – 145 million per annum by 2010.Cargo traffic will cross 3.3 million M.T. by 2010.

Upgradation & Modernisation of Airports as per International standards will be the top priority

An investment of Rs.40,000 Cr. (US$ 9 bn) would be made in Airport infrastructure during the period 2006-07 to 2013-14.

material used with soil, rock or other geotechnical

related materials as an integral part of a man-made

project, structure or system

This term encompasses

Geotextiles

Geogrids

Geonets

Geosynthetic products at a Glance


Geosynthetic functions


Separation• Prevents contamination of granular material

• Reduces loss of granular material into sub-base

• Makes spreading of fill easier

• Minimise need for excavation or treatment of existing

ground

• Fill can be placed over soft ground


Filtration

• Geotextile Allows Controlled passage of

excess Pore water from the soft

subgrade.


Confinement

• Geotextile restrains lateral movement of

the material at the bottom of the

granular layer.


Definition :

A flat structure of synthetic fibers randomly laid

manufactured by bonding them together –

mechanical bonding , thermal bonding or chemical

bonding .

Erosion Control

- Shore/Costal Protection

- River & Canal Bank Protection

- On-shore structures

- River Revetments

- Dams & Flood Defence Bunds


PROBLEMS:

1. River and Canal Banks are subject to wave actions, i.e. reversing

flow conditions .It is this dynamic erosive force that undermines

bank stability and effects channel flow and/or navigability

2. On Coastlines, the three key agents of erosion are :

- Waves & Tides Eroding the shoreline

- Waves and tidal scour take the eroded sediment away from

the coast

- Currents sweep the displaced material out to the sea.


Solutions :


River Revtments


Shore/Coastal Protection

Advantage of Geosynthetics

Geotextile filter, being permeable allows water to pass

through releasing water pressure but prevents soil erosion.

With specialised built- in factory –controlled Hydraulic and

filtration properties a single layer of geotextile can replace a

succession of stone filter layers.

working under water is much easier because the filter system

can be assembled above the water and lowered into position

with less time being used.

Geotextiles is easier to install either manually or mechanically.


Required characteristics of the

filtering geosynthetic

The filtering geosynthetic was designed in order to achieve

the following purposes:

- Good filtering capacity (Appropriate Hydraulic properties)

- Impact resistance (must be Robust)

- Holding resistance

- Resistance to the construction stress (Good Puncture & Tear Strengths)

GeoComposites :

(a) Drainage Composites

Terram 1BZ Terram DC-1C, DC-1D & DC-1E


Geotextile filter is a very important component of Drainage

Composite. The Heat-Bonded geotextile on Terram 1BZ outperforms

other geotextiles by providing:-

• Higher chemical resistance

• Higher modulus

• Higher available strength at working strains

• Higher elongation at break

• Higher resistance to installation damage

• Constant hydraulic properties over a period of time

The use of Geosynthetics in cost effective track structure design


Railways


Geosynthetics

- Why remains Untapped Potential ?

Or

- Reasons for Low Growth in India ?

? ? ?


- Lack of proper awareness and Close interactions and participation between manufacturer/Supplier, Design consultant/specifiers & end user (Civil Contractors, Govt. authorities etcs.).

- Non availability of dedicated Indian code i.e Dependency on foreign code

- State level agencies lack awareness and many of Govt. agencies remain oblivious about the new products including Geo-synthetics due to improper information , lack of knowledge for advantages of use, low budget etc.

- Preparedness of end users designers to go with traditional ways or custom made solutions.

- Lack of proper testing and evaluation

- Non-availability of trained and experienced Staff.

Hurdles Observed


- Unified Indian code, Specification is the need of the hour.

- The use of Geosynthetic should be mandatory as it’s now proven technology – This means inclusion in all SOR’s , guidelines etc.

- To conduct practical training, Seminars and Exhibitions.

-Manufacturer should step forward with best quality with proper testing at economical cost – This also means best cost needs high volumes as well.

- Availability of proper testing at National level.

- To generate technically trained personnel. - Geosynthetic should be included as a subject

or course at BE level.
