88 PERFORMANCE OF BRIDGES Intended Benefits The use of HPC is intended to extend the service life of the bridge by reducing cracking and permeability. Use of the material also promises benefits during bridge construction and element fabrication.

APPENDIX B 89 the required height of approach spans or increase underpass clearances with savings in earthwork. By replacing a percentage of the cement, the supplementary cementitious materials used in HPC can lower the cost of the concrete mix and reduce the project's carbon footprint.

90 PERFORMANCE OF BRIDGES vibration process during placement. SCC is formulated to self-consolidate during placement, thus eliminating the human factor to ensure complete consolidation.

96 PERFORMANCE OF BRIDGES application to protect against corrosion. Evaluation results indicated that the systems did not perform as intended.
|
From page 97... ...
APPENDIX B 97 Example Projects California's (CA-2001-05) White's Hill Sidehill Viaduct project used HPS in plate girders of the new bridge for high strength; longer spans allowed for eliminating piers in an active landslide area.

From page 98... ...
98 PERFORMANCE OF BRIDGES cast-in-place construction after the use of ABC becomes standard practice. A historical example of such cost savings for prefabrication versus castin-place construction is the use of pretensioned concrete I-shaped beams, which became standard practice more than half a century ago because of their economy and quality control relative to cast-in-place beams.
