REHABILITATION OF ROAD LINKING UMUEKULUMMIRI STREET TO IMT AWARNESS GROUND JUNCTION IMT CAMPUS III ENUGU

ABSTRACT
This project entitled “Rehabilitation of Road” is aimed at investigating the causes of failure on the road linking Federal Secretariat, IMT Civil soil lab to Industrial Centre IMT Campus III Enugu and the possible way of re-designing it for its effective use by IMT community and visitors of IMT.  But before the road is being re-designed, effort was made to find out the causes of the road failure along this road which includes lack of drainage system, lack of maintenance, inadequate thickness of the wearing course and poor quality control during the construction of the road.

Furthermore, Reconnaisance and preliminary survey which includes leveling and traversing were carried out along the centre line of the road.  Soil tests were also carried out in the laboratory which helps in finding out the causes of the road failure and the possible way of getting it re-designed.  The soil tests that were carried out includes: mechanical analysis, compaction test, Atterberg limit test and California Bearing Ratio (CBR) test.
Finally, I therefore recommend this project materials very essential for lecturers, researchers and other students that will carry out their project on the topic “Rehabilitation of Road..
