Abstract:
Field mixing and placement of ultra-high-performance concrete (UHPC) on bridges with traditional methods and equipment is often a time-consuming process, involving small batch sizes, the transport of fresh material with concrete buggies, top forming and overfilling deck-level UHPC connections, grinding the cured UHPC overfill, and curing UHPC overlays with plastic sheeting. Steelike, Inc., working with contractors on UHPC projects over the past few years, has introduced a number of new techniques that simplify UHPC construction and reduce time and cost, eliminating some or all of the aforementioned steps. Recent projects that incorporated these techniques will be presented, showing how the innovative techniques saved contractors time and money.
