Abstract
In this paper, applications of Markovian transition probability model to decision of optimal maintenance strategy of flexible pavements on network basis are discussed.
The optimal maintenance strategy at the project level is formulated based on both dynamic progrmming and the equivalent annual maintenance cost. These two methods give the exactly same optimal maintenance level for the minimum long-run expected average cost.
Introducing the concept of repaired ratio, the optimal strategy at the network level is formulated as budget allocation problem by expansion of the equivalent annual maintenance cost model at the project level.
