Evaluation of Latex-modified and Silica Fume Concrete Overlays Placed on Six Bridges in Virginia

Report No: 01-R3

Published in 2000

About the report:

Latex-modified and silica fume concrete overlays were placed on six bridges on I-95 south of Emporia, Virginia, in the fall of 1994. The construction was funded with 20 percent Virginia Department of Transportation maintenance funds and 80 percent special ISTEA Section 6005 federal funds specifically allocated to demonstrate overlay technologies. ISTEA funds were also used to evaluate the installation and initial condition of the overlays and to prepare this report. The overlays are in good condition after 5 years in service and are protecting the reinforcement from further chloride-induced corrosion.
