CHAPTER ONE
INTRODUCTION
The importance of road to life and
activities can not be overemphasized. Roads have important role to play
in the transportation system of the country. Good transportation system
through the pavement design has in the recent years provide to be of
much significance commercially and otherwise history testifies that the
provision of roadways is necessary to draw a country out of a state of
uncivilization, but that civilization is not attained until good road
network between neigbours is made so easy that the local difference
which brench narrowness is minimized.
However this project has been
designed strictly to modern design standards e.g ASSHO method and it
centers on the route survey and pavement design of the road to meet with
the present day effective services.
Moreover, this project work
could really sever as a future guide in making a new rural road, down to
industrial layout to connect mass comm..
Therefore being in a school
environment a good transportation system will improve the healthy
studying condition of the new road pavement and maintenance of the
existing one.
1.1 RELEVANCE OF PROJECT
The roadway linking Federal
Secretariat industrial centre and Mass Communication Department is an
earth road of about 0.620km in length whose origin can be traced back to
the origin of the I.M.T campus III environment.
The project work has
its relevance centered on the general design of a roadway which will
link federal secretariat, industrial centre and Mass communication
Department in order to ensure a hitch free traffic especially to the
lecturer, visitors and students making use of that industrial centres
However
the improvement of this roadway would grieve the students and lecturers
the service of belonging as it gives easier access to masscom.
Department.
1.2 SITE INSPECTION
This project site which is the
roadway linking Federal Secretariat industrial centre and Mass
Communication Department was inspected to ascertain its location and the
present state of the road. It was vividly observed that the area was a
dusty roadway throughout its length and had been graded without
siderains, spanning about 620m length with the width of 85m.
To
obtain these information, a preliminary survey was carried out which
also helped to ascertain the geological and soil conditions likely
intervals forming the chainages to be referred to until the construction
id\s brought to a completion.
1.3 EVALUATION OF ROAD NETWORK W NIGERIA
There are three types of roads in Nigeria
- Grade I: Surface dressed road
- Grade II: laterite on natural soil road
- Grade III road on nature soil
Road,
which were built earlier in Nigeria, were built as grade III roads,
which consist of roads built on level earth. This grace of road was
subsequently improved to grade II roads, which comprises of stone
laterite on soil and on general surface roads.
Ultimately, the road
was improved to grade I which is laterite road with good surfacing. The
surfacing is either asphalted concrete for flexible pavement (in this
project work flexible pavement will be considered).
The progressive
method of road construction produced very durable roads but because of
this rapid growth of traffic on the grade I and II this method of road
construction was discontinued and surface dressed roads were built.
Road
development receive a set back due to the development of railway in the
country between 1895 and 1910 but was only revitalized early 1960when
highways were built to connect various party of the country. Today,
there is virtually on state capital (if not local government area
headquarter) that is not linked directly by a highway.

ABSRACT - [ Total Page(s): 1 ]This thesis on a project undertaken by the author is aimed at providing explanation of the basic theory of the work of road design and its associated activities also, to cover practical methods of working.In pursuit of the meaningful completion this project a lot of investigation was embarked with principles and practice of road construction. The total distance of route was determined and stations established bearing in mind the intervisibility of the stations.Leveling was carried out to obtain ... Continue reading---
