Use of UHPFRC (ultra high performance fiber reinforced concrete) cast-in-situ over-lays for repairs and strengthening of bridge decks is already quite a widely used technology, while use of this method for strengthening of bridge supports is still much less often. This paper describes the first use of this technology for bridge abutments in the Czech Republic, and if we know well, also the first use of such a ribbed over-lay internationally.
