ARAMID FIBERS USED FOR REPAIR AND STRENGTHENING OF EXISTING BRIDGES

The paper presents the experimental tests designed to improve the existing techniques of bridge repair by the combination of external prestressing and aramid fibers (AFRP). The external prestressing substitutes the damaged prestressing steel and aramid strips will play, in the repaired bridge, the role of the corroded reinforcing steel. In a first group of tests, the bonding properties between aramid and concrete are found to be good, both from the static and dynamic points of view. The test performed in a two-span (7.5 + 7.5 m) box-girder prestressed concrete model, where the ultimate load obtained in the repaired beam almost equals the ultimate capacity of the model before damage was produced, shows the feasibility of the repair technique in heavily damaged concrete bridges.
