Ultra-high performance concrete (UHPC) is a relatively new type of concrete that exhibits exceptional compressive strength (30,000 psi+), has incredible durability, is fast-setting, self-consolidating, and can develop the yield strength of a #5 black rebar with as little as 5 inches of embedment. The Federal Highway Administration (FHWA) has completed (and continues to perform) various tests on this material; all with very favorable results.
One application that FHWA is currently promoting is to use UHPC as joint-fill material. This basically involves building a bridge deck using individual precast concrete deck panels that are "glued" together at the job site using the UHPC material. This allows a bridge deck to be built/re-built in a fraction of the time as a typical cast-in-place deck system. This new system evolved in response to the FHWA's recent initiative to implement Accelerated Bridge Construction (ABC) wherever possible. New York State is the front runner right now and has performed over 40 bridge deck replacements using this type of system.
