ABSTRACT

The main goal of the paper is the presentation of research works on static and fatigue behaviour of LWC (lightweight concrete) deck slab reinforced with GFRP (glass fibre reinforced polymer) rebars. The structural LWC with lytag type aggregate has been used for slab casting. The carrying capacity of the slabs as well as fatigue durability have been checked during experimental tests on three full-scale deck slabs. All slabs were 5.2 m long, 1.9 m wide and 0.18 m deep. One- and two-span arrangements have been applied for static and fatigue tests in shear and flexure. The research has clearly revealed that bridge deck slabs made of LWC concrete and GFRP rebars could be viable alternative for conventional concrete bridge decks with steel rebars. Following the research the first Polish application of LWC bridge deck slab reinforced with GFRP bars took place on a medium-size road bridge.
