Book excerpt: For wood to work successfully in external environments, it must be treated with chemical preservatives. This study determined the effect of various oil- and water-based preservatives on the performance of stress-laminated Southern Pine bridge decks. This 2Â-year study was limited to one species for the wood laminations and one type of stress laminated system. Nine half-width, full-length stress laminated test decks were constructed of Southern Pine lumber. Each test deck was treated with one of seven preservatives and outfitted with one of three bar anchorage types. Moisture content levels did not change significantly throughout the monitoring period, which implies that the wood had achieved moisture equilibrium prior to testing. According to this study, when Southern Pine stress laminated bridge decks are properly designed, (1) the anchorage system has a negligible effect on bar force retention and (2) water-based preservatives may be successfully used to treat these bridge decks. We recommend that the design guidelines currently available for stress-laminated decks treated with oil-based preservatives be extended to decks treated with water-based preservatives and constructed with any bar anchorage system. This recommendation is based on the similarity of the behavior of water- and oil-based preservatives in the stress-laminated test decks treated in this study.

This book was released on 2007 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timber material repair and replacement cost for timber bridges is a considerable expense to highway agencies in Iowa, especially to county road departments. To address these needs, the objectives of this investigation was to study the field effectiveness of various treatment alternatives used on Iowa roadway projects and to determine if the current specifications and testing are adequate for providing proper wood preservation. To satisfy the research needs, the project scope involved a literature review, identification of metrics, questionnaire survey of Iowa counties, on site inspections, and a review of current specifications and testing procedures. Based on the preservative information obtained, the following general conclusions were made: Copper naphthenate is recommended as the plant-applied preservative treatment for timber bridges. Best Management Practices should be followed to ensure quality treatment of timber materials. Bridge maintenance programs need to be developed and implemented. The Iowa Department of Transportation specifications for preservative treatment are the regulating specification for bridges constructed with state or federal funding in Iowa and are also recommended for all other bridges.
