About the event

This presentation covers the Pavement Condition Study which established, by county and nationally, the lengths and areas of regional roads requiring remedial works.  A total of 13,055km comprising 673 regional road routes were surveyed as part of this study, involving the use of machine surveys to collect road condition and skidding resistance data and digital imagery on the regional road network.

It is clear that there has been a substantial improvement in ride quality on the Regional road network over the seven year period of the study.  Nationally, the percentage length of the Regional road network in the Road Reconstruction category has dropped very significantly from 24% in 2004 to 15% in 2011. At local authority level, there is considerable variability in the distribution across the remedial works categories. 

The outturn condition parameters comprised a number of key pavement performance indicators. The key indicators were visual rating (VR), international roughness index (IRI), rut depth, mean profile depth (MPD) and SCRIM coefficient (SC). The condition parameters are reported for each 100 metre length of the entire regional road network.   The visual rating was carried out from high definition video used to capture the road surface condition and using a newly developed 1 to 10 rating system for Irish roads.
