6. INTRODUCTION  Aziz Cross project is a signal free interchange with partial clover leaf system and two additional directional ramps. Clover leaf interchange Partial Clover leaf interchange with two directional ramps instead of loops

7. INTRODUCTION  There are normally 32 conflicts at any interchange which are completely resolved at Aziz Cross. 32 No. Traffic Conflicts Traffic Count 2014

9. BASIC COMPONENTS OF FLYOVER Bridge cross-section can be divided into two portions. 1. Super Structure This portion receives the live load directly. For example, Box Girder 2. Sub Structure This Portion supports the entire structure and live loads.  Piles  Pile cap  Piers  Abutments Web Web Pier Canopy Pier Shaft Pile Cap Pile Pile Pile Super Structure Sub Structure

10. CONCRETE PILES A pile is a vertical structural element of a deep foundation which transfers super structure loads to the earth farther down from the surface to a subsurface layer.

11. PILE CAP PILE CAP Pile cap is a thick reinforced concrete mat that rests on concrete piles that have been casted into ground. concrete pile cap distributes the load of the superstructure (from piers and abutments into the piles. Pile Cap Piles Pier

12. PILE CAP AND PIER PIER A pier is a reinforced, raised structure in form of pillars typically supported by well-spaced pile caps. It transfers the loads from deck to pile caps. For this project, special shape of pier is adopted. It as two components 1. Pier Shaft as column 2. Pier Canopy as transom Pier Canopy Pier Shaft Box Girder

13. Abutment refers to the substructure at the ends of a bridge span. It supports;  Super Structure load  Live Load  Lateral Earth Pressure ABUTMENTS Abutment Pile Cap Piles

14. REINFORCED EARTH WORK  Reinforced earth wall is earth retaining structure and provided at approaches (from road level to bridge level).  The key components of a Reinforced Earth wall are geo-strips, granular backfill and precast concrete facing panels.  The frictional bond between the backfill supports the lateral earth pressure and stresses induced due to traffic load.

17. PRE-STRESSED BOX GIRDERS Bottom View of Box Girder Piers  An optimal and most efficient design of beam is box girder. A box girder consists of enclosed tube with multiple walls.  The advantage of a box girder is that it better resists torsion. Having multiple vertical webs, it can also carry more load than an I-shape girder of equal height. Pre-stressing Mechanism
