Threshold-based Maintenance Optimization for Pavement Infrastructure using Hybrid Dynamic Modeling

This study adopts hybrid dynamic modeling (HDM) to simulate and optimize threshold-based pavement maintenance. To evaluate the quality of the optimized threshold-based maintenance, benchmark plans are also generated by relaxing the threshold-based strategies. The proposed methodology is demonstrated with a network of 20 highway pavements. Based on the numerical results, some guidelines for selecting maintenance strategies in different scenarios such as budget availability are proposed.
