1. HIGWAY ENGINEERING Session 05 Subject: S0012 / Introduction to Civil Engineering Year: 2007

2. Bina Nusantara

3. Definition Highway engineering is the branch of civil engineering  concerned with design of pavement structure, design of geometric alingment for safe highways and road. Highway engineering became popular after the World War in 20 th Century

4. Bina Nusantara Scope of Work Pavement Engineering Design Asphalt Testing Material Geometric for Alignment Design Road Construction

5. Bina Nusantara Pavement Engineering Classification : 1. Flexible Pavement 2. Rigid Pavement 3. Composite

6. Bina Nusantara Flexible Pavement Flexible pavements. Those which are surfaced with bituminous / asphalt materials. These types of pavements are called "flexible" since the total pavement structure bends or deflects due to traffic loads. A flexible pavement structure is generally composed of several layers of materials which can accommodate this "flexing".

7. Bina Nusantara Flexible Pavement Surface Base Subbase Subgrade P ( Load )

8. Bina Nusantara Rigid Pavement Rigid pavements. Those which are surfaced with portland cement concrete (PCC). These types of pavements are called "rigid" because they are substantially stiffer than flexible pavements due to PCC's high stiffness.

9. Bina Nusantara Rigid Pavement Surface Subbase or base Subgrade P ( Load )

10. Bina Nusantara Rigid Pavement JOINT

11. Bina Nusantara Composite Composite. Those which are surfaced with portland cement concrete (PCC) and bituminous / asphalt materials as overlay construction

12. Bina Nusantara Asphalt Testing material Using for Testing asphalt material

13. Bina Nusantara Geometric Design Vertical and Horizontal Alignment basic geometric elements of road design, including: chainage, profile grades, vertical curves, circular and spiral curves, and superelevation.

14. Bina Nusantara Road Construction – flexible pavement

15. Bina Nusantara Road Construction – rigid pavement

16. Bina Nusantara Subjects Highway Engineering Learn about : – Pavement design – Geometric Design – Material design & testing (for Lab. activities )

18. Bina Nusantara Failure Construction West Sumatra - Earthquake Norwegia Cracking Distress-USA

19. Bina Nusantara Social and environmental effects Community cohesion: Where highways are created through existing communities, there can be reduced community cohesion and more difficult local access. Consequently property values have decreased in many cutoff neighborhoods, leading to decreased housing quality over time. Noise Pollution  Highways generate more roadway noise thanarterial streets due to the higher operating speeds. Air Pollution issues  Highways may contribute fewer emission than arterials carrying the same vehicle volumes. HOV ( high Occupancy vehicle ) lanes
