used to adjust all future costs in the analysis to a present value. These adjusted costs can then be combined with the initial construction cost to give a total present cost for all the activities over the life cycle analysis period. Total present costs for all alternatives can then be compared to decide on the most economical pavement alternative.

Life Cycle Design: Concrete –Most studies estimate product service life for concrete pipe to be between 70 and 100 years. Steel –CSP usually fails due to corrosion of the invert or the exterior of the pipe. Properly applied coatings can extend the product life to at least 50 years for most environments.

Structures are often damaged due to the prolonged operating lifetime, exposure to natural hazards, and degradation phenomena. When the structure is expected to be efficient for a long time, Life-cycle cost analysis (LCCA) is recognized as one of the suitable tools for the performance assessment (Lagaros 2007; Chiu et al. 2010).In addition, for designing structures, it is necessary to consider
