The most used mode of transportation in Nigeria is road while flexible pavement is the most constructed on the roads. This project work is all about carefully assessing the condition of the flexible pavement on some selected roads, determine some causes of the failure on the selected roads in Ola Oluwa Local Government area of Osun State, South-western Nigeria. The visual assessments of the pavement were carried out through Pavement Condition Survey and the drainage condition of the selected roads. Disturbed soil samples were taken from the failed and unfailed portion of the roads and their geotechnical properties determined. After the thorough assessment of the pavements on selected roads it can be concluded that the failures on the roads are due to non-functioning drainage facilities, poor design, non-standard construction materials and poor maintenance culture.

Keywords: Flexible pavement, Pavement Condition Survey, disturbed soil samples, geotechnical properties.
