This presentation summarizes the key aspects of an elevated road project in India. It includes three main points: 1. The elevated road project has a total length of 1250 meters with two lanes, crash barriers along the sides for safety, and approaches built with retaining walls. 2. The main components of the project are site clearance, earthworks, construction of foundations for piers and abutments, building the superstructure with pre-stressed concrete girders and deck slabs, and construction of service roads. 3. Testing was performed on site to check the workability and strength of concrete used in building the foundations, piers, and other structural elements. Slump tests were used to

2. NEED FOR CONSTRUCTION
 To improve traffic management
system.
 To reduce hindrance to traffic flow.
 By increase the volume of road,
chances of accidents get reduced hence it
will act as a life saving drug.

6. The primary components of the project include:
1. Site clearance.
2. Earth Work and Excavation .
3. Shifting of utilities.
4. Construction of Open foundation for pier & abutments.
5. Construction of RCC T Beam & PSC Girders & Deck Slab

6. Construction of retaining wall.
7. Construction of embankment and subgrade in
approaches.
8. Construction of service road.
9. Construction of roadside unlined drain.
10. Construction of diversion road including culvert.
11. Providing road sign & markings.
12. Providing road illumination required.

7. TEST PERFORMED AT SITE AND SITE
LABORATORY
(a) At site of work:- Slump test for measurement of
workability of concrete.
(b) At site laboratory:-
(i) Compressive strength test of concrete .
(ii) Grading of aggregates-Sieve Analysis Test.

8. SLUMP TEST FOR WORKABILITY OF CONCRETE
Most common method for measuring the consistency &
uniformity of concrete.
APPARATUS REQUIRED FOR TEST:
• Cast iron mould in the form of frustum of cone having internal
dimension:- Bottom diameter : 20cm
Top diameter : 10cm
Height : 30cm
• Tamping Rod of 16mm
diameter.

9. Foundation For piers and abutments
• Types of bridge foundations-
1. Open foundation
2. Well foundation
3. Block foundation
Open foundation & Block foundation are come
under shallow foundations .
well foundation are come under deep foundations.

10. Open foundation
• Types of open foundation-
Isolated , combined, and strip footings.
Raft foundations.

14. Pre-Stressing
 Pre-stress concrete is
the one in which there
have been introduced
internal stresses of
such a magnitude and
distribution that the
stresses resulting
from given external
loading counteracted
to a desired degree.
Pre-Stressing

15. SUBSTRUCTURE
 PIERS & ABUTMENTS
Piers and abutments are the vertical structures supporting
deck,girders,bearings providing for transmitting their load along with
live load coming over bridge to the bed/earth through foundation.
