Technical and Economical Comparison between Roller Compacted Concrete and Asphalt Pavement and Prioritizing Effective Parameters Using Hierarchy Analysis Model and Fuzzy Hierarchical Analysis Model (Case Study¬: Sari Pelazh T junction to Bahnamir)

There is no perfect and precise procedure when selecting the type of road pavement, but you must take many factors into account when choosing the type of street pavement, here are some of them: traffic density, cost, type of soil, climate conditions, materials, durability, repair and maintenance, and environmental issues. This research aimed to technically and economically evaluate and compare Rolled compacted concrete, with Asphalt pavement. In this study, we used hierarchy analysis model and fuzzy hierarchical analysis model for technical comparison, and Executable map issued by department of transportation of Mazandaran province, for economic comparison. These criteria include pavement effective life time, effective exploitation, durability, resistance, performance speed, performance procedure, cost of performance (economical), repair and maintenance, and environmental issues for technical comparison. Finally ,hierarchy analysis model and fuzzy hierarchical analysis model, dually compared  and showed that Asphalt pavement with less weight took the second place, and Rolled compacted concrete with almost three times more weight took the first place as the better pavement and better choice. Prioritizing technical parameters in hierarchy analysis model and fuzzy hierarchical analysis model were as follows: durability as the first priority, resistance as the second, cost as the third, effective life time effective exploitation as fourth, repair and maintenance as fifth, environmental issues as sixth, performance speed as seventh, performance procedure as the last one. Comparing economical cost of Rolled compacted concrete with Asphalt pavement according to executive map issued by General Directorate of roads and urban development of Mazandaran Province, showed that performing Rolled compacted concrete costs 45% less than asphalt pavement.
