A study has been made in Ghana of the effect of road maintenance on road performance. This report gives the results of measurements of the condition of unsealed roads made over a period of more than two years. The effects of the maintenance activities of grading and dragging on road surface conditions are assessed. During the study some of the running surfaces deteriorated sufficiently to significantly increase road user costs. Roughness was the aspect of running surface condition which had most effect on vehicle running costs. (Copyright (c) Crown Copyright 1983.)
