The paper is presented the method,
scope, results and their analysis of the research, and the main conclusions
drawn from static field load tests performed on a five-span prestressed
concrete road bridge after its
repair. The bridge with the effective spans of
18.00 m is located over the Nysa Klodzka river in Paczkow (Poland). All bridge
span beams became reinforced by CFRP tapes glued on bottom flanges of main
beams as well as overlaid a new concrete deck layer. The main aim of the
conducted bridge repair was to increase its load capacity to 300 kN (class C)
according to the Polish Loads Standard (PN-85/S-10030). The results obtained
during the research of the bridge after its repair at field load tests were
conducive to determining the behavior of the analyzed span structure under
static loads, which allowed for an assessment of the efficiency of the
strengthening, as well as establishment of guidelines for future reference
concerning this type of maintenance in the engineering practice.
