From page 7...
... Desk research and stakeholder interviews indicated that UHPC-C adoption is tied largely to the use of PBEs and accelerated bridge construction (ABC) , a method of building bridges from PBEs or prefabricated bridge units that include a precast deck and supporting members, such as steel or concrete girders connected on site, and is quicker and reduces traffic delays.

From page 8...
... Several owner agencies indicated they maintained a general convention, if not a standard, for using UHPC-C when adopting PBEs for bridge decks. However, no interviewees said their state had broadly adopted PBEs and ABC methods.
