Is recycled asphalt a good product to use for driveways?

Yes, it does. Recycled asphalt will bind together and firm up when it’s laid at the right depth over a solid base and then compacted with heavy rollers. If the base is soft or the material isn’t properly rolled, it will stay loose and behave more like gravel. Recycled asphalt is crushed old tarmac that still contains a bit of bitumen, the black sticky binder that held the original road together.

Once it’s spread and rolled, the pieces interlock, and the remaining bitumen helps them knit into a tighter, more stable surface rather than loose chippings. Traffic and weather then help it to bed in, so you’ll usually find it continues to tighten and harden over the first few weeks and months.

Yes, recycled asphalt is usually cheaper than concrete for the same area. It costs less to buy, and it’s quicker to lay, so your labour bill is lower too. Concrete tends to last longer, but if you’re trying to keep upfront costs down, recycled asphalt is usually the better.

A recycled asphalt surface will only go properly hard if: It’s laid on a sound, well-drained base, not soft or muddy ground.

The layer is the right thickness (commonly around 75-100 mm for driveways), so it can compact evenly.

It’s compacted thoroughly with the right machinery (typically a vibrating roller or plate), ideally in warm, dry conditions.

Done well, recycled asphalt can harden into a durable surface that withstands heavy traffic and adverse weather.

Recycled asphalt, often referred to as Reclaimed Asphalt Pavement (RAP), is a material derived from the milling or removal of old asphalt pavements. It is processed and reused in new asphalt mixtures or for various other applications in construction.
