Abstract

In present, Thailand Department of Highways (DOH) manages pavement maintenance activities based on the result of pavement performance evaluation module and appropriate treatment selection using economic analysis module. These modules still have a few limitations. For instance, these modules are unable the formula and assumptions according to current situation, and do not consider budget limitation. Thus, this research has created the model for pavement maintenance planning, which can consider pavement performance with economics criteria as well as budgeting to find the optimized plan for pavement maintenance in multi-years period.
