Description
Summary:The first step in prioritising district road maintenance is to identify the key maintenance criteria based on each road's actual condition, as retaining unsuitable and insignificant criteria and deleting more significant ones leads to inaccurate and unreliable decisions. The objective of this study was to acquire an expert consensus on the key criteria for the prioritisation of district road maintenance in the Iraqi infrastructure sector. To achieve this objective, a group of 13 specialists was assembled to assess a list of 34 district road maintenance criteria using the Fuzzy Delphi approach. These criteria were thus organised into seven groups based on their relative importance. The first group included the seven criteria deemed to be the most important: "Potholes”, “Cracking”, "Transverse slope”, “Shoving", "Depressions", "Bumps and Sags", and “Patching and Utility Cut Patching". This study's findings should thus aid decision-makers in this sector in terms of making appropriate decisions for the prioritisation of district road maintenance.
