| Outline of Final Research Achievements |
In this study, IRI was measured and stocked to build proper prediction model in three countries such as Kenya, Tanzania, and Uganda in Africa, and Cambodia, Laos, and Myanmar in Asia. Asia-Africa trans road networks.
Finally it was found that deterioration of pavement occur much faster in urban area with heavy traffic and repair was completed at short intervals. It was also found that conventional prediction models were verified but there was not significant different among them and proper selection of the model is important according to its purpose.
