Optimal Maintenance Fund Allocation Models for Network Level Asphalt Pavement Management Systems

Abstract:

In this study,a set of optimal maintenance fund allocation models are established to cope with different desirability levels of pavement conditions at the network level for asphalt pavements.Corresponding to low,middle and high levels of pavement condition desirability,the proposed fund allocation models can adapt to the decision-making processes of the authorities and reduce the computational burden.Case studies indicate that the models can effectively solve the pavement maintenance fund allocation problems.This study also shows that classifying the pavement condition desirability levels and establishing corresponding analysis procedures can provide solid foundations for the future demand of maintenance funds.
