Abstract: Wood that is exposed to moisture is vulnerable to attack by decay fungi and insects. Covered bridges were designed to prevent such biodeterioration by keeping the wood dry. However, protecting all bridge members from moisture is difficult, even in well-designed and well-maintained covered bridges. Members used in the abutments near the ends of bridges are especially vulnerable. Other areas may also be exposed when leaks go undetected or vandals remove cladding that protects the bridge interior. In all these situations, the integrity of critical bridge members can be extended by field application of preservative treatments. In this research project, we are developing a guide that will allow bridge maintenance personnel to select and effectively apply appropriate in-place treatments.
