Abstract
An experimental investigation compared repair methods that could be used to repair timber piles in timber pile bridges. Five full-scale timber pile specimens with different levels of damages were prepared. The damage in each specimen was repaired with fiberglass-reinforced plastic wrap to encapsulate the damaged region, which was filled either with resin or grout or with resin and gravel. Ultimate load tests were carried out on the specimens to evaluate the effectiveness of the repair methods. Test results showed that grout was more effective than resin in repairing large cavity-type damage. Resin appeared to be more effective in repairing cracks and small cavities in timber piles. The failure load of the repaired pile specimens was at least five times greater than the design load capacity of the timber piles and indicated that the repair methods effectively restored the capacity of the damaged timber piles.
