• Abstract:
  A study was implemented to assist the Alaska Department of Transportation and Public Facilities (ADOT&PF) with life cycle costs for ; the Alaska Highway Bridge Inventory. The study consisted of two parts. Part 1 involved working with regional offices of ADOT&PF to ; assemble bridge costs (initial, construction, maintenance and repair) for a sample of bridge types. Results were limited by available data ; and format; therefore, it is recommended that ADOT&PF develop an available online simple Bridge Management archiving system. ; Part 2 focused on identifying how a bridge scheduled for replacement deteriorated over time. Load tests were conducted to help assess ; the bridge response of an aged structure. Noticeable and measurable differences in strain at the end of the bridge life for the structure ; studied were found. ; A service life cycle costing approach has advantages over a traditional life cycle cost approach. For example, a bridge has essentially ; three lives; structural, functional and service. Structural life can be extended almost indefinitely with the right repairs. The service life ; approach does not assume a life. Rather it used to estimate a life that provides the lowest life cycle cost. A service life approach allows ; comparisons of alternatives for an infinite planning horizon.
