Hence, taking into account RUCs within analysis approaches would yield propose the most appropriate and cost-effective M&R alternative. This revealed the importance of RUC in the Life Cycle Cost Analysis (LLCA) of different M&R actions tale place on highways. Results showed that RUCs were approximately 10 times higher than RACs on each route of the selected roads network. Calibrating the HDM- 4 as well as collecting the required information, the long-term effects of preservation alternatives associated with their costs were evaluated and compared.

Towards this end, the HDM- 4 Software was employed to calculate costs using localized data. The latter is the primary reason for excluding RUCs in the economic analysis.

A number of complicated parameters are involved in RUC estimation. The main contribution of the paper was to demonstrate the importance of RUCs in long-term economic analysis and planning of future M&R activities. RUCs are divided into two main categories namely, Vehicles Operational Cost (VOC) and Travel Time Cost (TTC). The research aimed to calculate, and compare Road Agency Costs (RACs) with Road User Costs (RUCs) resulted from certain types of M&R interventions on a selected roads network located in eastern part of Iran. Lane closure owing to the implementation of M&R operations incurs enormous costs on road users. Pavement inefficiency in carrying the applied load from passing vehicles results in spending significant costs on continues Maintenance and Rehabilitation (M&R) treatments. Rapid growth in a number of vehicles on roadways accelerates pavement deterioration trends.
