Project description

This study uses the Weibull disatribution to determine threshold time to failure, Weibull shape factor (index of performance curve) and scale factor for each of the successive maintenance rehab activities for 60 year design. It retroactively evaluates current network sections in benefit/cost, incremental benefit/cost and life-cycle cost. Study recommends increasing reliability through parallel design (e.g., drainable base and joint sealant) rather than serial design, e.g., thicker sections
