1.1 AIMS AND OBJECTIVE OF STUDY
The major objective of this
investigation is to ascertain factors that likely lead to the failure of
Eliozu-New Airport road in Obio/Akpor L.G.A. of River State in
particular and Nigeria Highways in general and how it affect national
stability and development. This project work stand at a point to unveil
the very facts behind why most of the roads fail soon after
construction.
The count carryout will broadly provide information on
the actual traffic volume and the capacity of traffic and will help in
used for possible traffic planning and design.
It shall lead in
proper construction of highway and remedy that will possible give a
lasting solution and reduction in road failures. The several test such
as test on asphalt, test on soil will provided better facts to the cause
of the failure of the case study.
1.2 SCOPE OF THE PROJECT STUDY
The whole section of the road was visited (Reconnaissance) and failure pattern noted.
The project scope includes:
- Assessment of kind of failure and causes on the Eliozu-New Airport road.
- Soil samples collection and testing and analysis to determine the sub-grade, sub-base strength of the road foundation.
- Assessment of underground water level and its affect on the pavement.
- Assessment of traffic capacity intensity on the networking plan of the road and volume determination.
- Assessment of drainage condition and proper drainage provision.
- Assessment of the proportion and amount of bitumen and finer used in the Asphalt mixture used for the surface course.
- Classification of the soil according to ASSHATO classification system.
- Enumeration of possible pavement distresses that are found along a road section.
1.3 BACKGROUND INFORMATION OF THE STUDY AREA
The
location of which this investigation is been carryout is a road network
located at Obio/Akpor L.G.A at the out script of Port-Harcourt, River
State. The road is from Eliozu junction to Airport road leading to Elele
of which concentration is lay on the Eliozu junction where ABC shuttle
is, at where over head bridge is undergoing construction currently to
where the Eliozu-New airport road intersect with the airport road.
1.4 LIMITATION OF THE STUDY
This
research was carried out under the limits of the available material and
resources. The work is centre on soil sample testing and
classification, asphalt testing and traffic volume and effect of
groundwater on road bases.
The following factors hinder the prompt attainment of this project work.
- Lack of laboratory facilities
- Cost of the project work
