| 摘要： | A framework for a pavement management system employing mechanistic performance submodels for pavement behavior is presented. These performance submodels explain the development of the physical distresses in fundamental terms. This approach enables the individual distress modes to be addressed in pavement management strategies. It also forms the basis for a dynamic programming optimization scheme. The performance submodels are based on a reliability formulation incorporating full-distribution uncertainty information of the variables. They provide the transition probabilities for the optimization that determines the optimal strategy for rehabilitation from a set of alternatives subjected to management and operational constraints. The optimization also yields the expected annual performance in terms of the distresses and the expected capital outlay required to implement the strategy. |
