Road authorities require pavement information and decision support tools to assist them in the management of their asset, particularly in determining the budgets and maintenance that are needed on their network. This report covers the modelling methodology and processes that have been developed and implemented in a pavement cost model for the National Roads Authority, Ireland.

The model has been developed so that the reference data and imported network data link into a workspace, which is then used as the calculation space during an analysis. A user can choose to create a range of different analyses in order to provide answers and associated sensitivity analysis to issues such as how much budget is needed to maintain the network in a steady state.

The modelling process is detailed within this report, along with the rules and algorithms used. This includes the steps of ageing data and identifying treatments through to selecting and costing maintenance schemes in the chosen network.
