The Case Against
 “Worst-First” Strategy
•Pavements typically selected for treatment are those that are closest to failure
•Quickly depletes available funding focusing on streets where most cost is already the case
•Meanwhile, acceptable streets slip into “needing major rehabilitation”
•Backlog quickly grows to a point of no recovery
•When funding constraints are present, preventative maintenance and worst-first strategies are incompatible
