3. Purpose of Access Road:
1. Facilitate the movement of farmers to and from
the backlands
2. Access route to arable farm lands for cultivation
3. Low volume roadway
Geometric Configuration:
Length = 3 miles ( km)
Width = 22 ft ( m)
4. The Access Road in Lucknow Rural Areas
Look at this
road…I ain’t
going deh!
8. The statement of problem is to design a new
pavement structure for the access road in
Lucknow that could fulfill all the traffic and
environmental conditions while at the same
time being an economically viable structure.
9. Quantify and characterize the loadings of the various
vehicles that uses the current facility
Investigate and evaluate the potential of suitable pavement
alternatives for a cost effective alternative to
accommodate the present and future traffic loads on the
road
Evaluate the potential advantages and disadvantages of
pavement alternatives
Carry out life cycle cost analysis on the various pavement
alternatives to determine the most promising alternative
Design proposal of a suitable access road based on the
most promising pavement alternative

16. The pavement alternatives evaluated ranged
from flexible, semi rigid to cement treated
pavements
The most viable pavement alternative is the
cement treated pavement since it is the most
cost effective pavement structure while
optimizing the level of service to the road
users
17. • India's economical growth plan of over 6% per annum for
the next 20 years will, to a great extent, depend on an
efficient road infrastructure, not only national highways
but other roads too, including link roads for rural
connectivity, which can provide fast movement of goods
and people with safety and economical cost to the user.
government of India has drawn up Pradhn Mantri gram
Sarak Yojana(PMGSY) for implementation of rural
connectivity. it is estimated that in the next 7 years, road
works under PMGSY worth Rs. 1,20,000 crores are to be
constructed . Since road pavements are an important part
of these projects, costing about 50% of the investment , a
careful evaluation of the alternatives is necessary to make
the right choice on a rational basis, which may be
comparatively more beneficial to the nation.
