| Research Abstract |
In this research, in order to investigate the deterioration and current condition of main root in east African countries, simple measurement system, VIMS, was applied. Among the east African countries, we conducted trial measurement on main root in Kenya, where VIMS system is officially adopted. In this measurement, we confirm that the system can be applicable in this country and current state of the pavement was evaluated. In Tanzania, main root around the capital of Dar Es Salam was investigated and the system is under the review of Tanzania National Road Authority for official equipment. In Uganda, main root around the capital of Kampala was investigated. Finally it is found that VIMS is sufficiently applicable in these east African counties and the roots around the capital are relatively good but in the local area the roots are not properly managed. Thus in the future we can evaluate the state of deterioration of pavement in east Africa using the initial data that we obtained in this time.
