An Evaluation of TYFO S Fibrwrap

State Departments of Transportation (DOTs) are continually looking for cost effective products and processes to extend the life of any number of transportation related products. Salt splash and leakage from bridge joints are the cause of a significant amount of spalling, cracking, and deterioration affecting the structural integrity of bridges around the state. This damage applied to bridge columns for example, deteriorates the confining effects necessary to counter compressive forces. A common approach in addressing this problem is encasing the column in an outer diameter of new concrete, usually approximately twelve inches thick. The solution has been effective, but expensive. Rather than employ a standard concrete encasement, in June of 1994 the Vermont Agency of Transportation applied TYFO S Fibrwrap to columns of the first pier of Bridge #60 in Williston while rehabilitating the bridge. Based on performance observations conducted by the Agency, TYFO S Fibrwrap appears to be a viable alternative to concrete encasement as a rehabilitative method for concrete bridge columns.
