Development of Metals Corrosion Maps of Arkansas and Maintenance of Cross-drains

项目名称：	Development of Metals Corrosion Maps of Arkansas and Maintenance of Cross-drains
摘要：	Cross-drains are considered one of Arkansas Department of Transportation (ARDOT's) most valuable assets. However, metal culverts or pipes used in cross-drains along or across the Arkansas highway system are susceptible to significant corrosion. The rate of corrosion varies around the ARDOT districts, and it depends on various material properties and environmental conditions, which include soil type, groundwater table, rainfall, acidity level of soils, etc. Catastrophic incidents such as a complete washout of metal culverts along with roadway can be prevented if proper metals can be selected during the construction project. A user-friendly corrosion map will help to reduce such catastrophic damage and save human life and properties. Therefore, the objective of this study is to develop such user-friendly corrosion map for all ARDOT districts by analyzing relevant historical soil, materials and environmental data. Required mathematical models followed by user-friendly maps will be developed to accomplish the goals of this study. This study will also look into the maintenance prospective of cross-drains to help prevent future damage to roadway. It is expected that the findings of this study may save the department on costly repairs.
