This document provides details for the design of a 108km rural road passing through three districts in Badakhshan Province, Afghanistan. It includes typical road cross sections for different terrains, geometric design values, structural pavement design, drainage structures, retaining walls, and a list of centerline coordinates and elevations. The road requires excavation, embankment filling, asphalt and gravel surfacing, drainage features like culverts and drains, and retaining walls given the mountainous terrain with elevation changes up to 1350m along the route.

been prepared as part of the reserved matters application
submission for the site at Baharak Road which has out limit
approval ref. This report will seek to address condition of
management and planning section of the design. As part of
the basic road design the road has been divided to different
practical stages to use the smart link and objective resources
in case.

10.  The proposed Road is located in the South East side of Badakhshan Province. The
alignment of the access road passes through Baharak district. The area is hilly, not
flat or level. There is need for more cases of land donation in this project because it
has surrounded by river mountainous terrain and green land. The road width is
about 11m. The road needs cutting, filling, Sub- base course, base course, Asphalt
carriageway and Double Bituminous Surface Treatment (DBST) with side drain
and construction of structures (Culverts, Retaining and breast walls (Stone
masonry and RCC), Washes, Bridges (RCC, PC) along the road.
 The construction of this road needs, roadway excavation, road way embankment
filling, side cutting (Lose, Soft, Rock and Hard rock materials) asphalt surfacing,
DBST surfacing, gravel surfacing, side drain (earthen, stone pitching, Rip Rap and
lined), culverts (Pre- Cost and cost in place) and fords.
10

11.  As it is knowing that the road length is 108 km and it passes through three districts
Baharak (1150 m from sea level), Wardooj, Zebaak and Eshkashem (2500 m form
sea level). and the highest elevation is 3000 m form sea level. The elevation
difference from start to end is almost 1350 m, which show high rate of elevation
changes. And the road sections are located in different terrains like flat, rolling and
mountainous.

12.  The AASHTO “A policy on Geometric Design of Highway and Streets” 2011 and
Overseas Road Note 6 “A Guide to Geometric Design” published by the Transport
Research Laboratory (Overseas Unit), 1988 was also consulted, which gives
guidance on geometric design.

13.  For safe and smooth ride and increasing the safety factor in the entire length of the
road only to the sharp curves based on AASHTO 2011 A policy on Geometric
Design of Highway and Streets widening have applied as per below table. The
design vehicle WB-19 has considered. The widening need to be applied both in
inner and outer side, but due to the mountainous terrain we have consider only the
inner side.

Although Superelvation is beneficial for
traffic operations, various factors often
combine to make its use impractical in
low-speed urban areas. These factors
include:
 wide pavement areas;
 the need to meet the grade of adjacent
property;
 surface drainage considerations;
 the desire to maintain low-speed
operation; and
 frequency of intersecting cross streets,
alleys, and driveways.

18. 18
Considering the characteristics of the
soil of the existing embankment and
which is likely t be used for the
construction of the earth embankments.
 Normal Cut 1:1 with no benches on
any stages.
 Lose materials cut 1:1 with benches in
6m height and 3-meter width with 4.0%
to ward earthen drain.
 Hard materials cut 0.4:1 disturb by jack
hummer.
 Hard Rock materials cut 0.1:1 disturb
by blast.
 Composition materials for cutting Big
hard rock exist in Lose materials.
