Transportation



Transportation Engineers design and analyze

– – – – – –

Roadways Railways Airports Waterways Parking Lots Traffic Control Signal Systems.

ROADWAYS

Classification of Roadways –



According to IRC

– – – – –

Expressway National Highway (NH) State Highway (SH) Major District Road (MDR) Village Road (VR)



According to Material used for Construction

– – – –

Bituminous Road or Tar Road Concrete Road Water Bound Macadem Road (WBM) Earth Work.

Classification according to IRC

Expressway – (HW) ???????

National Highway –

–

Run through LENGTH and WIDTH of Country

– – – –

Connects Capitals 2 Lane Width – 7 to 15 m Fast and Heavy Loaded traffic.

State Highway –

– – – –

Connects Major Cities to NH 2 lane or some times 1 Width – 7 to 10 m Used for fast Traffic

Major District Road –

Connecting District places to taluka, main cities, major market places in cities - Width 5 to 8 m - Use of Moderate Traffic

Village Roads -

- Connects Village to taluka, village to nearest railway station, village to village… - EARTH ROAD or KUTCHA ROAD - Light and Slow moving Vehicles - (Bullock Cart Road)

Home Work ------- Write min 3 Examples of each type of Roadways according to IRC…

Classification based on Material

Classification based on Material

Bituminous Road or TAR Road

– – – –

Tar is a Binding Material Easily Repaired and Maintained Due to Bitumen Layer Wearing surface is small Life is Short

Concrete Road - Wearing surface is Cement Concrete - Rigid Pavement - Life is High as strength is high.

- Difficult to repair and Maintain - HIGH COST.

Water Bound Macadam Road -

– –

Base Course of Bitumen or Concrete Constructed with 2 to 3 layers of aggregates and soil material

–

Normally provided on VILLAGE ROAD Earth Road –

– – –

Earth material is main Constituent of the road Kutcha road (Loacally available material) Formed by trace passers or bullock carts….

Any 6 Applications of TRANSPORTATION ENGINEERING???

RAILWAYS



It is also called as ‘ PERMAENT WAY’ Cross Section of Permanent Way.

Gauge:

-The Clear Distance between the inner faces of Rails Indian Railways are divided in 3 types based on Gauge Broad Gauge 1.676m

Meter Gauge Narrow Gauge 1.000m

0.762m

I.R. divided in Different 8 Zones 1) Northern 2) Central 5) Western 6) North Eastern 3) Southern 4) Eastern 7) South Central 8) South Eastern

HOME WORK…..

1) Short Note on Construction of Permanent way?

2) Comparison between ROADWAYS and RAILWAYS…… (4 mrks)

Geotechnical OR Soil Mechanics

 Geotechnical engineering is essential for a safe and secure structure.  Deals with SOIL Study  Behavior of Soil under applied LOAD  TESTS – Trials Pits Plate Load Test

Application of Geotechnical Engg.

1) 2) 3) 4) 5) 6) 7) 8) Properties of Soil Classification of Soil Bearing Capacity of Soil Design of Earth Dam ------EG??????

Study of different SOIL STRATA Capability of SUB- GRADE of road.

Design of FOUNDATION in any type of soil Analyze the WATER SEEPAGE for Dams

Quantity Surveying

 Deals with measuring various Quantities and Probable cost of Construction.

 CLASSICATION: Quantity Surveying ESTIMATE VALUATION

Estimation

cost’

– To find/ Calculate the of Construction.

‘approximate

Valuation –

Determining the

‘PRESENT VALUE’

of existing property.
