Project Objectives/ Outcomes
To carry out a pavement condition study on the entire Regional road network.
The Department of Transport, Tourism and Sport (DTTAS) contracted with PMS Pavement Management Services Ltd (PMS) to carry out a pavement condition study on the entire Regional road network in 2018. The contract was administered by the Road Management Office (RMO) on behalf of DTTAS. The pavement condition study involved the use of machine surveys to collect road condition data, skidding resistance data and digital imagery on the Regional road network. The main objective of the 2018 Pavement Condition Study, carried out under the “Contract for the Provision of Road Condition Survey and Assessment/Analysis of the Regional Road Network”, was to establish, by local authority and nationally, the lengths and areas of various categories of Regional roads requiring remedial works.
A total of 13,150 kilometres comprising 686 Regional road routes was surveyed in one direction as part of the 2018 study. The pavement condition data was collected in accordance with the “Mechanical Road Condition Survey Specification for Regional and Local Roads in Ireland” The road condition data (RCD) was collected using two Road Surface Profiler (RSP) machines. The skidding resistance data was collected using two Sideways-force Coefficient Routine Investigation Machines (SCRIM). The data collection of the road condition data was completed over a 26 week period from April to September 2018.
The outturn condition parameters comprised a number of key pavement performance indicators. The key indicators were visual rating (PSCI), international roughness index (IRI), rut depth, mean profile depth (MPD) and Characteristic SCRIM coefficient (CSC).
The visual rating was carried out from high definition video used to capture the road surface condition and using the Pavement Surface Condition Index (PSCI) 1 to 10 rating system.
