The data below shows the breakdown of Good, Fair, and Poor condition RS pavements since 1988. These values are determined by a combination of IRI and Traffic Volumes. The percentage of poor RS pavements has been steadily decreasing since 2003 and is now at its lowest recorded level (9%). This means that 91% of all RD pavements are in Good or Fair condition.
