Description
ABSTRACT
This project report is a study carried out to determine the causes and remedies to road deterioration. A case study of Naze Junction to Futo Gate Road, this study talks about the existence and development of tacks, researches made to discover the causes and remedies of road deterioration, the road structure/road maintenance.
This project covers the methods used to determine the cause of the road deterioration by conducting, soil test and traffic census. It includes the pictures of the deteriorated spots of the road. The result of the test done and their general analysis.
It covers also the conclusion of the study causes, based on the literature search and results of experiments and finally the recommendation of the study.
INTRODUCTION
The importance of highways for the prosperity of any country cannot be over emphasized. The development of roads starts a chain reaction of atomic nature. It opens up new avenues or increases employment in the agriculture, industry, commerce health and sanitation sector by inherent virtue of being a communication and transport link between the developed areas.
The road, so necessary an instrument of social well being that in every new country it is one of the first things that is being thought of. The great essence or need for roads came about due to the invention of the wheel, some 5,000 years ago. The increasing rate of highway deterioration has become a source of great concern to both the Engineers and the people using it. There is a great need to ascertain the various causes of the deterioratory state of our roads. And some of the ways to ascertain the causes of deterioration is to carryout trial bore hole,site investigation, and also traffic census.
The major reason for unsatisfactory state of road construction in Nigeria, is the low priority given to road development and maintenance, also responsible, is the lack of concern for human life and proper qualification and experience to do a particular job. The construction of roads, require expert’s in the field, so that the road will be able to carryout its basic function effectively, and survive its life expectancy of years. This is in order to avoid the premature failure of our roads, which is an existing fact currently in Imo State, particularly on the road leading from Naze Junction to Futo Gate which forms the basis of this project. There is not just one type of road failure, so the issue of the premature deterioration of our roads requires finance, and experienced knowledge.
