Project Details

Project Abstract: 

Several studies have already been completed from the previous year’s research effort identifying preservative treatments, fumigants, fire retardant treatments, and remedial treatments: Identification of Preservative Treatments and Fumigants for Treating Historic Covered Bridges.Effect of fire retardant treatments on covered bridges.Remedial treatments for field treating timber bridges. These have been separate studies that need to be reviewed and relevant information extracted to produce a guide for engineers in selecting and treating timber members for these historic structures.

Goals

The objective is to develop a guide identifying chemical wood preservatives for use by engineers and bridge preservationists that maintains historic integrity yet remain effective.
