1. A beam for use in construction of a long span bridge structure comprising:
a reinforcing member having a geometric configuration selected from a group consisting of: a “U” tub beam with composite deck system; a decked I-beam; and an adjacent box beam;
said geometric configuration formed of a UHPC mix having:
an initial compressive strength, f′ci=10.0 ksi;
a compressive strength at service, f′c=17.4 ksi;
a modulus of elasticity of concrete, Ec=6500 ksi;
a residual rupture stress, frr=0.75 ksi; and
a concrete unit weight, wc=0.155 kcf; and
said UHPC mix further comprises a plurality of discontinuous fibers distributed randomly throughout a concrete matrix, said plurality of discontinuous fibers formed of a material selected from the group consisting of: steel; polypropylene; nylon; polyvinyl alcohol; polyolefin; polyethylene; polyester; acrylic; aramid; carbon; silica glass; basalt glass; glass fiber-reinforced polymer; and basalt fiber-reinforced polymer.
