The essence of this project work is to look into the causes of highway failure and the different types of failure which are presented along the Eliozu - New Airport road in Obio/Akpor L.G.A in River state, taken as a case study. Some factors identify as being responsible for the failure of the chosen road section includes, poor sub grade soil with questionable material. Ground water study is carried out, which give insight to it effect to the failure of the flexible pavement, lack of drainage facilities, improper pavement design, poor compaction and traffic volume increase and lack of maintenance are critically taken into consideration.
Traffic volume count and soil test analysis and test on asphalt such as extraction-gradation test, are properly carryout, of which it result gives an adequate insight to the various causes of the failure situation experience along the road section through this investigation, show that relative to pavement, base course, wearing course and sub base were to less than the requirement for effective functionality of the said road of case study. From the investigation carryout, useful recommendation are made to improve the design and proper ways of reducing the rate of failure in Nigerian highways.

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE INTRODUCTIONIn construction of highway, generally the roads are not
designed to last forever. It is been designed to serve some purpose for a
specific time. As it can be seen in engineering work, the life span of a
road is always an important factor that must be taken into
consideration as one of the criteria for the construction. This really
depends on the factors like construction procedure and consideration,
the soil water relationship, quality of workmanship during th ... Continue reading---
