Asphalt Overlay

asphalt overlay

An asphalt overlay must be placed on a structurally sound surface.

Asphalt overlay may be required.

Over time, asphalt pavement starts to lose the oil and finer aggregate leaving a surface that is rough.  At this point a sealcoat is no longer a cost effective solution for maintenance.

An overlay is when a new asphalt surface, placed at a minimum thickness of 1″, is installed over your existing asphalt surface.  An asphalt overlay must be placed on a structurally sound surface.  For this reason any failures including wider cracks are first cut out and patched prior to the placement of the overlay.  Tie ins to existing

“Tack oil” is applied to the existing surface to promote bonding before the asphalt is placed and compacted.

surfaces around the overlay are typically addressed by cutting them out and replacing them lower to allow for the newly overlaid asphalt surface to tie in flush with gutters, ramps, and surrounding asphalt that is not being overlaid.

Armour Pavement will first repair and create the tie ins in the area.  Next the area will be swept clean of all debris and loose aggregate.  Then a light coat of “tack oil” is applied to the existing surface to promote bonding.  Lastly the asphalt is placed and compacted.

Once an overlay is completed then a pavement preservation plan should be put in place.
