    LIFE CYCLE COST ANALYSIS OF PAVEMENT (LCCA) is detail study of transportation project relating pavements starting from its design phase to its entire service life. It determine the total cost and value of item over the entire cycle along with pavement thickness and type. The cost of road construction includes design expenses, material extraction, construction equipment, rehabilitation and maintenance strategies. In this project a stretch of 24km national highway of BUTWAL, NEPAL was considered and various data like pavement performance, traffic, and climatic condition, economic indicators were collected and integrated. Flexible pavement was designed for design period of 10 year with maintenance of 15 years and was compared with rigid pavement designed for period of 30 years to finalize optimum performance of pavement based on pavement cost and strain, stress analysis. Based on above study we conclude that the initial cost of rigid pavement is 28% higher than the initial cost of flexible pavement but these costs get balanced during the entire 30 year life since more durability and serviceability is provided by the pavement
