All major resurfacing schemes are prioritized following a visual inspection, on a countywide basis.
Condition data is then applied to the areas of carriageway/footway/cycleway covered by the bid and the schemes are ranked according to the worst condition, taking into account the results of various condition surveys, including deflectograph, SCRIM, CVI, DVI and SCANNER surveys.
An enhancement factor is applied to the R&R scheme bid based upon the maintenance hierarchy and not the classification. This factor is applied to these schemes to indicate the greater importance of the higher categories of highway usage.
For further information on the various survey types and the factors applied to the maintenance hierarchy for the categories of highway, please follow the links on the left hand side.
