In Taiwan, the decision-making processes of pavements highlight more on the costs and sometimes intimidate the uses of new materials and technologies. This study is proposed to introduce the concept of life-cycle cost analysis (LCCA), which is an economical tool promoted to be used on highway investments in modern western nations. The LCCA approach calls for including not only direct agency expenditures, but also costs to facility the users that result from these agency activities. Also the LCCA enables the total cost comparison of competing design (or preservation) alternatives, each of which is appropriate for implementation of a transportation project. The historical agency data for maintaining pavements were collected and analyzed to subtract information on agency costs and performance records. The user cost was incorporated into the LCCA by using values in literatures as well as provided by relative local research works. As a result, this particular study presents a 10 year comparison of life cycle costs between rigid and flexible pavements by using historical data. A 40 year comparison of life cycle costs was also predicted among three different alternatives for maintaining typical freeways in north Taiwan.
