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.

Guidelines for the design of stress-laminated timber decks have been published by AASHTO, but they do not provide comprehensive information on materials, construction, and inspection. Therefore, this document presents: (1) background information on timber bridge materials and their quality control; (2) a comprehensive step-by-step design procedure based on the 1991 AASHTO Guide Specification; and (3) guidelines for construction, field monitoring, inspection, and maintenance procedures. Potential fabrication problems are discussed, and an inspection checklist is included.

As the timber bridge design has evolved, some engineers have been concerned about the integrity of the stress-laminated system in cold climates. The structural integrity of a stress-laminated bridge depends on the level of interlaminar compression (between the wood laminations). Temperature change can cause material shrinkage, which could lead to substantial performance problems based on material mechanics and the nature of the stress-laminated system. In this study, to determine the effects of thermal change on interlaminar compression, four stress-laminated timber deck sections were put through a warm--cold--warm cycle. Various interlaminar stress levels and three moisture content levels were tested. Results showed that interlaminar compression in stress-laminated decks of this size was not affected by extremely cold temperatures when the moisture content was less than 19% and when initial bar force was sufficient.
