Functional failures and structural deterioration defects are among the leading causes of growing failure probabilities of the road systems and networks. Thus, asset maintenance intervention is an essential task for the unified management of road assets and systems. The objective of this research is to consider reliability based probabilistic approach established on functional failure mode, effects and criticality analysis parametric reliability analysis, risk-based assessment and strategic asset deterioration decisions. The combined progressive assessment frameworks and algorithms based procedures utilize service inspection, safety inspection and survey inputs. The illustrated reliability maintenance based methodologies offer sustainable asset management for highway transport infrastructure and systems with emphasis on resolutions to their functional failures, defect related risk and appropriate deterioration treatment.
