Performance and Constructability of Silica Fume Bridge Deck Overlays

Pages : 478
Book Description
The effects of construction practices and material properties on the performance of concrete bridge decks are evaluated. Emphasis is placed on comparing bridge decks with silica fume and conventional concrete overlays and determining if the silica fume overlays commonly used on bridges in Kansas are performing at a level that justifies the extra cost and construction precautions. Forty continuous steel girder bridges, 20 with silica fume overlays, 16 with conventional overlays and four with monolithic bridge decks are included in the study.

Book Description
Concrete structures such as bridge decks, with large surface area relative to volume, shrink and crack, thus reducing service life performance and increasing operation costs. The project evaluated the early, first 24 hours, and long-term, 180 days, shrinkage of Virginia Department of Transportation overlay and A4 general bridge deck concrete mixtures. A modified ASTM C157 prism was developed to measure the early-age shrinkage, as was a unique hygral cylinder test. Long-term shrinkage was measured using the ASTM C157 prism test. In addition, scaled bridge deck overlay specimens were cast to assess cracking potential. Overlay mixtures tested were latex modified mixtures using portland cement, Type K cement, an expansive mixture and portland cement, fly ash and microsilica blend. Deck concrete mixtures evaluated were fly ash, slag, Type K cement and an expansive mixture. Recommendations for controlling shrinkage at 3, 7, and 28 days were developed for all overlay and A4 concrete mixtures.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 423: Long-Term Performance of Polymer Concrete for Bridge Decks addresses a number of topics related to thin polymer overlays (TPOs). Those topics include previous research, specifications, and procedures on TPOs; performance of TPOs based on field applications; the primary factors that influence TPO performance; current construction guidelines for TPOs related to surface preparation, mixing and placement, consolidation, finishing, and curing; repair procedures; factors that influence the performance of overlays, including life-cycle cost, benefits and costs, bridge deck condition, service life extension, and performance; and successes and failures of TPOs, including reasons for both.
