Field Investigation of Concrete Overlays Containing Latex, Silica Fume, or Pyrament Cement

C. Ozyildirim

This study evaluated latex-modified concretes (LMC) and concretes containing silica fume (SFC) or Pyrament-blended cement (PBCC) in bridge deck overlays in the field. The condition of the overlays was monitored for 4 years. LMC and SFC were placed in 2 days using a vibratory roller screed spanning half the width of the bridge, each side in 1 day. PBCC was placed in small segments, each covering half the width of the bridge, in 2 months. The placement in small segments was directed by traffic control requirements. PBCC was used with no admixtures. Similarly, LMC was used with no admixture except the latex-modifier.
