“…A global overview of Figure 1 shows the existence of two main groups of standards for fiber reinforced concretes: The first group includes the international standards, such as Spanish national standard, 12 MC2010, 9 and the draft version of the new EC2 13 . These documents introduce fiber‐reinforced and high‐performance concrete as a variety of conventional concrete, but there is no specific consideration for the UHPFRC. The second group gathers national standards and guidelines for UHPFRC: French national annex to the Eurocode, 14,15 Swiss code SIA 2052, 16 documents from the Federal Highway Administration, 17 Walraven et al UHPC textbook, 18 and the draft recommendations by the fib about UHPFRC 19 . These documents focus on fine‐grained cementitious materials with high compressive strength and a predominant hardening response at the postcracking stage under tensile stresses. …”

High‐performance fiber‐reinforced concrete (HPFRC) can be considered a promising material for the construction of precast concrete girders for road bridges. This paper presents conceptual considerations and numerical analysis to support this statement. The HPFRC is a compromised alternative between FRC and UHPFRC mixes. Specifically, a tailor‐made mix design of HPFRC jointly developed by ACCIONA and the authors is presented, and then compared with the other types of fiber‐reinforced concretes collected from the technical literature. In addition, some trends observed in the database are described. This material characterization is followed by a conceptual analysis of the advantages of the application of HPFRC to road bridges. Specifically, a proposed bridge for the case of a 60 m‐span box girder is analyzed. A comparison between alternatives based on the use of HPFRC and conventional reinforced concrete is discussed. The results shed light on the viability of this material for bridge application. Specifically, the main finding show potential significant material savings in structural elements of the superstructure. Finally, ongoing and future research for a wide application to the construction sector are briefly discussed.
