Abstract

Further to static test on aged RC bridge slabs strengthened with TYFO glassfibers, fatigue tests have been done on aged RC bridge slabs with and without glassfibers. It can be seen from the test that fatigue behaviors of aged RC bridge slabs stiffened with TYFO glassfibers have been by and large improved comparing with those of aged RC bridge slabs without TYFO, but fatigue failure modes have not been changed become of bonding failure between tensile reinforcements and concrete. It is in particular noted from the test that bonding failure between concrete surface and TYFO have been observed. Further tests are strongly necessiated to develop appropriate anchoring method for improving fatigue life of aged RC bridge slabs strengthened with TYFO glassfibers.
