Heavy precipitation events can lead to widespread flooding and prolonged inundation of road pavement which in turn would weaken its structural performance and accelerate its deterioration. A major challenge for road authorities is to prepare a suitable and swift recovery programme to restore the road network in the event of flood-related disruptions. Furthermore, widespread damage caused by flooding and other competing needs for recovery resources imposes additional constraints. The sit-uation is exacerbated by the uncertainty and complexity of the post-flood situation. To address this challenge, a methodology for the formulation of a strategic post-flood pavement recovery programme based on life cycle analysis is proposed in this paper. The resultant road conditions associated with the choice of work standards, the timing of implementation, as well as funding constraints were evaluated in a case study and a cost-effective recovery programme was formulated. The case study also demonstrated the use of output data to assist road administrations in strategic decision-making. This study serves as a guide for road administration to develop a post-disaster recovery programme and provides insights for further research into post-disaster management of infrastructure systems.
