Design control and criteria October 15 Design of Nablus Tulkarm Highway 8 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: o From station to station v = 110 km/hr o From station to station v = 100 km/hr o From station to station v = 90 km/hr

Design control and criteria October 15 Design of Nablus Tulkarm Highway 9 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.

Pavement Design October 15 Design of Nablus Tulkarm Highway 10 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.

Design Criteria for Horizontal Curves October 15 Design of Nablus Tulkarm Highway 14 Radius As design speed equal 110 km/hr the superelevation equal 6%  R min = 560 m. As design speed equal 100 km/hr the superelevation (Table 3.14 Equal 6%  R min = 435 m. AASHTO 2001) As design speed equal 90 km/hr the superelevation Equal 6%  R min = 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 Criteria for Vertical Curves October 15 Design of Nablus Tulkarm Highway 16 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.

Cross Section Element Design October 15 Design of Nablus Tulkarm Highway 18 The cross section elements are designed based on AASHTO recommendation to be as follow: 1. Lanes : 3.6 m for each 2. Shoulder: 2.5 m for each 3. Median: 3 m 4. Cross slopes: 2% (for traveled lanes) and 4% for shoulders. 5. Side slopes: 1:3 6. Sloped curb stones are used for median Cross Section Details 1. Guard rail 2. Ditches 3. Culverts

Intersection design October 15 Design of Nablus Tulkarm Highway 20 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˚  R min = 37 m, with offset=1.3 m, and taper 30:1 Sample of intersection deign shown below.

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 October 15 Design of Nablus Tulkarm Highway 25
