1. Civil Engineering Department Design of Nablus Tulkarm Highway Prepared by Ahmed Mohammed Mustafa Anas Zeyad Belbeasi Under the Supervision of Dr. Khaled Al Sahili Nablus- Palestine Dec. 2010 Design of Nablus Tulkarm Highway

2. Introduction • Road Description • Nablus Tulkarm Highway is a major road that connects two of the major Palestinian cities; Nablus and Tulkarm, with a length about 27 km. • The study case of the road is located between two Israeli checkpoints; Enab and Shefi Shomron checkpoints. with length is about 5.5 km. • The following Google Earth picture describe the study case of the road.

4. objectives • Evaluation of the exiting design • Redesign and improve the highway • Prepare Bill Of Quantities • Design all details related to the highway Design of Nablus Tulkarm Highway

5. Traffic studies • Three counts are conducted 1. Wed 2/6/2009 between 6:00 AM - 6:00 PM (Beit lead Intersection) 2. Wed 9/6/2009 between 6:00 AM - 6:00 PM (Tanib Factory) 3. Tue. 23/2/2010 between 3:00 - 5:00 PM (Tanib Factory) Design of Nablus Tulkarm Highway

7. DHV • DHV = 0.1 * ADT   Design of Nablus Tulkarm Highway

8. Design control and criteria • Functional classification Based on AASHTO, the highway can be classified as Rural Minor Arterial Highway • Design Vehicle based on vehicle classifications and AASHTO recommendations, WB-62 is chosen to be the design vehicle • Design Speed The highway is divided into three zones depending on the design speed: • From station 0+000 to station 2+700 v = 110 km/hr • From station 2+700 to station 3+200 v = 100 km/hr • From station 3+200 to station 5+421 v = 90 km/hr Design of Nablus Tulkarm Highway

9. Design control and criteria • LOS by analyzing the LOS for the two lane (which is the existing ) for a 20 years period, the LOS is founded to be E, which is not accepted for such highway. So, the analysis is done based on four lane and founded to be B, which is suitable for such a highway. Design of Nablus Tulkarm Highway

10. Pavement Design • part one (from station {0+000 to 1+250}, {1750 to 2+150}, {3+000 to 3+400}, and {4+300 to 4+700} ) will be designed based on CBR value of 3, part two (from station {1+250 to 1+750}, {2+150 to 3+000}, {3+400 to 4+300}, and {4+750 to 5+420}) will be designed based on CBR value of 20.

11. Design Considerations • Pavement performance ∆PSI = Pi – Pt = 2. • Traffic • Roadbed soil ( subgrade material ) and Material of construction and Environmental • Reliability ( R = 95 %, S. =0.45 ) 2.23 *10^6 Design of Nablus Tulkarm Highway

12. PAVEMENT DESIGN USING AASHTO METHOD SN=4.7 Mr = 4500 ESAL 2.23 *10^6 S0 =0.45 R% = 95%

14. Design Criteria for Horizontal Curves • Radius As design speed equal 110 km/hr the superelevation equal 6%  Rmin = 560 m. As design speed equal 100 km/hr the superelevation (Table 3.14 Equal 6%  Rmin = 435 m. AASHTO 2001) As design speed equal 90 km/hr the superelevation Equal 6%  Rmin = 335 m. • Super elevation It is assumed to be 6 % • Min. Length • L min= 3*110 = 330 m (for v = 110 km/hr) • L min= 3*100 = 300 m (for v = 190 km/hr) • L min= 3*90 = 270 m (for v = 90 km/hr) Design of Nablus Tulkarm Highway

15. Results of Horizontal Curves Design of Nablus Tulkarm Highway

16. Design Criteria for Vertical Curves • Terrain For Nablus Tulkarm Highway, the terrain where the road passes is level so, highway sight distance are generally long or can be satisfied. • Grade Since the terrain is level, in the project design the grade doesn't reach the max. grade which is 4 %, and also the min. grade is satisfied.

18. Cross Section Element Design • The cross section elements are designed based on AASHTO recommendation to be as follow: • Lanes : 3.6 m for each • Shoulder: 2.5 m for each • Median: 3 m • Cross slopes: 2% (for traveled lanes) and 4% for shoulders. • Side slopes: 1:3 • Sloped curb stones are used for median • Cross Section Details • Guard rail • Ditches • Culverts Design of Nablus Tulkarm Highway

19. Typical cross sections for part one Typical cross section for part two Design of Nablus Tulkarm Highway

20. Intersection design • All intersections in this project are “T” intersections. • The project contains 4 main intersections, which are : 1. Ramallah intersection 2. Beit lead intersection 3. Ramin intersection 4. Enab intersection The angle of all intersections is 90˚  Rmin= 37 m , with offset=1.3 m, and taper 30:1 • Sample of intersection deign shown below.

25. Recommendations • Adoption of suggested new design • The Drainage system should be improved . • Not to cot the trees that are located within the boundary of our road design, and replant these trees outside the road. • Give the accurate priority of the road. • make a maintenance program for the road Design of Nablus Tulkarm Highway
