Samenvatting
This report describes the performance of selected lengths of sealed roads in Ghana. The roads were monitored over a period of two and a half years, during which time very little effective maintenance of the carriageways was undertaken. The results of detailed measurements of road surface condition are related to the factors that cause pavement deterioration, and the important influence of the quality of surface dressing on pavement deterioration is emphasised. Examples are given of the user cost savings that can result from road maintenance, and criteria are suggested for determining when maintenance interventions on surface dressed roads in Ghana are required.
