Thin Layer Asphalt Overlay

If you’re looking for a faster, cheaper method of extending asphalt pavements and driveways, there is a better method than a full-scale repaving job.  Instead, you can do what is called a thin layer asphalt overlay.

You’re be pleasantly surprised to hear that these thin asphalt overlays are no more than 1.5″ thick or less and are made up of aggregate materials that generally have a small size:  about 12.5mm or smaller.

The catch, of course, is that thin layer asphalt overlays must be laid on base structures that are sturdy.

Remember that thin-lay asphalt overlay isn’t for everyone…it’s only when your base is good enough.

Recycled asphalt pavement, or RAP, can even be added into the aggregates to lower the cost and improve efficiency.  Not only that, but hot-mix apshalt is not necessarily needed:  warm-mix asphalt can add benefits, which allows the asphalt to be laid in relatively cool weather.

Most thin layer asphalt overlays can be expected to last a decade on a good asphalt base; about 6-7 years on a concrete base.
