Abstract
In the past, the design of the roads was mainly concerning the links between the major
cities and large towns in the West Bank. However, the access roads between villages
were not considered as the allocated budgets were limited. Recently, as the number of
population and vehicles increases dramatically, the existing relevant infrastructure
should be developed to fulfill the new requirements.
One example for such roads is A'sira ash-Shamaliya-Talluza access road which is
considered as an important link road is to be redesigned. The design and rehabilitation
of such road will contribute in minimizing the travel time and distance from/to Tubas
and Nablus governorates. Also, the project team suggest designing a new road
connecting between A’sira ash-Shamalia-Talluza connected road with Al-Badhan. The
project team contacted the Directorate of Ministry of Public Works and Housing in
Nablus city in order to collect the required data related to the project. The upgrading of
this project will enhance and encourage the mobility of the students and employers from
Tubas and surrounding villages and towns.
The functional classification of the road is local (access) road. The length of the section
to be upgraded is about 3km from A'sira ash-Shamaliya to Talluza village and around
3km from Al-Badhan to A'sira ash-Shamaliya-Talluza road. The new proposed design
is expected to solve the following existing problems in the targeted project:
• The width of the road is limited, the width of the existing asphalt layer is
approximately 6.5 m and the road are two-way/ two-lane road.
• The lack for appropriate shoulder.
• The lack of drainage facilities such as culverts, open and side ditches, no
manhole, and no subsurface drainage network.
• The lack in lighting across the road.
• The need for redesign of existing certain horizontal curves (sharp curve) and
high grade.
• The existing of different pavement distresses such as (alligator, longitudinal and
transverse, block, and edge) cracking.
• The terrain is difficult also there is valley which considered as nature reserve.
• The lack of a settlement plan in some areas for the new road
Finally, the design of the road includes horizontal, vertical, cross-section, and
calculating the quantities and total cost of construction. The American Association of
State Highway and Transportation Officials AASHTO 2011 standards and Civil 3D
Software are used in the design of the road. Moreover, the AASHTO 1993 method is
used in the design of pavement
