for Accelerated Bridge Construction or culvert replacement 1
Type of UHPC Mix Used: Self-leveling, self-consolidating, 2% steel fibers, 12,000 psi Method of Placement: Hand placement using buggies or wheel barrows Curing Time: 24 - 48 hours for full strength
Accelerated construction consisting of using precast concrete elements to replace aging structures:
- Bridges - Used for ABC projects where UHPC is used as joint fill material for connecting precast bridge elements (deck slabs, approach slabs, lateral diaphragm/abutment closure pours, haunch connections to structural steel, closure pours at intermediate piers and abutments.
- Culverts - Used in a similar manner for joining precast culvert sections (foundations, culvert to foundation connections, wing wall to culvert connections).
