Title: REPAIR OF TIMBER BRIDGE PILING BY POSTING AND EPOXY GROUTING
Accession Number: 00459579

Availability: Find a library where document is available Abstract: Evaluated in this paper is the repair of timber bridge piles by posting and epoxy grouting. The repair procedure consists of cutting out the damaged pile section and replacing it with a new section. After spiking the new section in place, the joints are epoxy-injected to form a permanent bond. The first phase of the study consisted of laboratory testing of repaired pile sections in both compression and bending. Full axial compression strength could be restored through the repair process; however, the ultimate bending strength could only be restored to typical allowable stress values. Flexural stiffness could also be restored to expected values for undamaged piles. To study the durability and long-term effects of the repair procedure, a field repair was also initiated. On a low-volume bridge located in a Louisiana national forest, three piles were repaired and instrumented. After 2 years, no significant movement or deterioration has been observed.
