Description
ABSTRACT
This project involves the route survey which includes: reconnaissance survey, theodolite traversing and leveling operations as well as soil tests which includes; plastic limit test, liquid limit tests and moisture content determination, compaction tests and California bearing ratio tests.
This project also involves the design of the pavement and the geometric design of the roadway.
INTRODUCTION
The relevance of road to life and its activities cannot be over emphasized.
Road is as old as the origin of man and plays a vital role in the life of the people in communities, states, countries. It is quite obvious that life would have been very difficult without the existence of roads. Nigeria for instance acknowledged the importance of road such that the local, state and federal government are all involved in the development and maintenance of road network.
History has shown that provision of roadway is a necessary tool for civilization. It advances prosperity increase and this bring about demand for better and faster communication facilities especially roads.
The continuing increase in Nigeria’s population has made the daily movement of passengers and goods an increasing complex problem.
