Estimation of the Remaining Service Life of Culverts

摘要: Culvert pipes play an integral part in transportation infrastructure since they facilitate safe drainage. A loss of culvert integrity could result temporary roadway closure and considerable rehabilitation/replacement costs or worse. In addition, the total collapse a pose major safety risk to motorists. Hence culverts should be routinely inspected condition state determined estimate remaining service life propose corrective actions so as prevent costly failures. The techniques are developed for estimating five types culverts: Brick/Clay, Concrete, Cast Iron, Corrugated Steel Aluminum. Condition State model that is used express extent deterioration, coupled with reliability analysis based upon Weibull culvert. cumulative distribution function failure normalized by design order decay curve into single material types. Based on inspection data it was concluded proposed theory represent performance different New Jersey. represents preliminary approach estimation culverts. Future research expected focus field studies obtain necessary cost parameters deteriorating perform statistical sample.
