Abstract (EN): To appraise the efficiency of the new strengthening technique by external bond of unidirectional CFRP systems, an experimental strengthening of a limited region of the top slab of N. S. da Guia bridge deck was proposed and performed. Four different CFRP systems were applied and instrumented with several strain gauges. Several field load tests were carried out using five discrete point loads to simulate the vehicle live load specified by Portuguese Code. The load tests were previously simulated in laboratory. With the present work, the authors, expects to contribute to clarify the knowledge of serviceability behaviour of this new strengthening technique, namely, when applied in the rehabilitation of reinforced or prestressed concrete bridges.
