4.2.1 TYPE OF PAVEMENT FAILURE DEFECT
There type of failure could be group into two (2) categories. These are functional failure and structural failure
FUNCTIONAL FAILURE
Functional failure is cause where the pavement cannot longer carryout it intended purpose (lead) depends on the surface roughness.
STRUCTURAL FAILURE
Structural failures are failure that indicated the breakdown of one or more component of the pavement structural.
In flexible pavement, structural failure may be classified under the following;
i. ALLIGATOR CRACK:
It is the first sign of pavement distress, the condition indicative of excessive movement of one or more of the underlying layer and of fatigue of the surface. It usually occurs in flexible pavement built over resistant 5-6 grade weak on improperly compacted base curse.
ii. RUTTING:
This is caused by consolidation of one of more of the purring layer or by exceedingly high axle load on a pavement that was under design inform as thickness in concern.
iii. SHEAR FAILURE:
These usually exist when cohesion and internal friction are lacking in the pavement base structure outside the tyre and sub-sequent cracking on the bituminous surface.
iv. LONGITUDINAL CRACK:
Here, the defect takes place essentially in horizontal direction due to lack of internal friction in the base or sub-grade soil. It is also due to volume change in sub-grade.
4.3 EFFECT OF FAILURE
The effects caused on pavement failure are as followed
i. It create inconveniency to the road uses.
ii. It create high rate of accident which usual occur at the point of failure.
iii. It promotes the rate of traffic congretion.
iv. It increases the level of highway robbery attack.
v. Land and properties level will not develop.
vi. It decreases volume of vehicle in the area.
4.4 CAUSES OF THE ROAD PAVEMENT IN EGBEJILA COMMUNITY AERA, ILORIN WEST LOCAL GOVERNMENT AREA KWARA STATE.
Failure that occur in Egbejila road and some rural road pavement in Ilorin west Local government Area are usually occurs on the road surface which are as the result of the following;
i. Inadequate maintenance of the road.
ii. Improper construction of drainage.
iii. Irregular or poor compaction soil.
iv. Improper planning of the road.
v. Poor material uses in base sub-base and the sub-grade.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTThis project was executed in order to investigate into level of service of Egbejila Road Ilorin west Local Government Kwara State and improvement options. It was carried out to determine the rigidity quality, traffic characteristics and traffic volume study of the road, which was put into consideration in order to know what really cause the failure and how to determine the improvement option for such road. It was also discussed; some of the possible effect of contraction which lea ... Continue reading---

CHAPTER ONE - [ Total Page(s): 2 ]In addition, it is essential to establish a technique that may be useful for determine relative accessibility of location in the road network. Ever when relative advantage are determined, there is need to develop models that will be useful for predicting commercial property values in Nigeria.1.4 SCOPE OF THE STUDYRoad may be classified as international, intercity or intra-city. International and inter-city road are usually major or arterial road, while intra-city road are routes within a c ... Continue reading---
