ABSRACT - [ Total Page(s): 1 ]This project investigates the primary causes of Road Pavement Failure and Possible Solution (a case study of Iree-Ibokun road). Various tests are carried out on soil samples colleted from failed areas of the road such as CBR test, sieve analysis test, liquid limit, Plastic limit test, Plastic index test and compaction test. The foundation failures of the road pavement observed are caused by excess ground water penetrated into the base and sub-base courses and geotechnical properties of the soil were also responsible for the failure of the road pavement such as: inadequate compaction, water inf

CHAPTER ONE - [ Total Page(s): 1 ]1.0 INTRODUCTION Road pavement construction has experienced many significant problems mainly in sub-base and base design and construction over the years in this country (Nigeria).Roads in Osun State have a very high volume of traffic which comprises of many type of commercial vehicles, cars and trucks. Roads have been constructed for more than 2000years. Even the earliest engineers practiced drainage of the pavement’s sub-surface layers in order to keep the highway functioning.
