Flexible pavement is a road pavement type which is commonly used, however rigid pavement is also widely used now days in Indonesia. It has even been used for local roads (managed by local authority), which take in heavy vehicle loads. This rigid pavement is used because it has longer service life and higher durability. The need for a durable road resulted in higher construction costs, whereas the budget for local road design and construction is often limited. This study aims to evaluate the agency costs that must be incurred for flexible and rigid pavement construction. Two alternatives of design life are simulated for each type of pavement, namely design lives of 10+10 year and 20 year for flexible pavement and design lives of 20+20 year and 40 year for rigid pavement. The agency costs of those alternatives are analysed using Life Cycle Cost Analysis (LCCA) program-RealCost 2.5. The results show agency costs for alternative flexible pavement 1 (design life of 10y + 10y) and alternative 2 (design life of 20 y) are $ 1,421,930 and $ 1,061,680 respectively. Furthermore for the rigid pavement, the agency cost for alternative 1 (design life 20y + 20 y) and alternative 2 (design life 40 y) is $. 443,990 and $. 350,870 respectively.
