Life Cycle Cost Analysis of Corrugated Metal Pipes in Arkansas
Publication: Tran-SET 2020
ABSTRACT
Metal culverts are being used by the Arkansas Department of Transportation (ArDOT) on a frequent basis. The service life of these culverts mainly depends on the properties of culvert materials and surrounding environments. The selection of pipe material at any location is mostly controlled by its life cycle costs (LCC), which include construction, operation, and maintenance costs. In this study, life cycle costs of different metal pipes are evaluated based on the existing unit costs data and other construction, maintenance, and user associated costs of a culvert. Laboratory investigations were carried out to assess the properties of the soils collected from different parts of the state. The secondary soil and water quality data were collected from secondary sources. Using neural network models developed based on secondary and primary data from state agencies, the electrical resistivity of soils has been predicted for different locations within the state. Then, the service lives of three different metal pipes were estimated. Finally, based on the service life of different metal pipes, their life cycle costs were estimated, and the geographical information system (GIS) based maps were developed for all 75 counties in Arkansas. The maps show the most feasible locations of different metal pipe culverts based on the associated life cycle costs. This study will help the ArDOT engineers to select cost-effective metal culverts for any location within the state.
