Abstract

The construction of new curbs or the replacement of existing ones is usually due to the need of installing safety or anti-noise barriers. Recent studies, developed by the authors and proven by experimental tests, have shown the effectiveness of a new technology, based on the use of high performance fiber reinforced concrete. This technology shows several advantages: a significant reduction in execution time of the curb and of installation of barriers elements, thanks to the rapid achievement of high resistance; lack of interference between barriers anchorages and reinforcement rebars. Aim of the study is the formulation of simplified procedures for the safety check of curb-slab systems, against the action of the vehicle impact, with reference to curbs rebuilding on existing reinforced concrete bridge slabs. Finally, safety check criteria of curbs, characterized by rectangular or L-shaped cross section, are proposed, based on both global and local behaviours.
