Samenvatting
The Virginia Department of Transportation's first modern experience with the construction of thin-bonded portland cement concrete overlays of existing concrete pavements through the use of fast-track paving is described. The study was conducted in cooperation with FHWA, and paving mixtures tested in a FHWA mobile laboratory were used.The study showed that the pavement could be overlaid and opened to traffic within 48 hr. Of special interest was the finding that the overlay concrete bonds to the base concrete with or without the use of a bonding grout.
