EVERYTHING ASPHALT Thin Hot Mix Asphalt Overlays

A tack coat should be applied to assure bonding of the thin overlay to the existing pavement. The hot mix asphalt materials are mixed at a hot mix plant, transported to the job site, placed using a paver and compacted with rollers.

Pavement Rehabilitation Through Ultra-Thin Whitetopping (UTW ...

For the UTW overlay, 2"- 4" of the existing asphalt pavement was cold-milled and then 4" of concrete pavement was placed. An UTW overlay is known as a thin (2"-4") concrete overlay bonded to a milled, existing AC surface.

Concrete Overlays: A Proven Option

For an unbonded concrete overlay on concrete, engineers usually design a thin separation layer of debonding material —typically a 1-inch layer of asphalt —to be placed over the existing concrete.
