Asphalt and tarmac are not the same thing. Traditional tarmac, short for tarmacadam, uses tar as a binder to hold crushed stone together. Asphalt uses bitumen—a byproduct of crude oil—to bind aggregate. Though tarmac was once a go-to for roads, asphalt has become the modern standard. And these days, most surfaces referred to as “tarmac” are actually asphalt. So, while the names may overlap, the key distinction lies in the binder—tar for tarmac and bitumen for asphalt.

If pavers are uneven but not sunken, lift the affected bricks and check the bedding sand underneath. In many cases, simply smoothing out or adjusting the sand is enough to level them. Add or remove small amounts as needed, then press the pavers back into place and tap them with a mallet until they sit evenly with the surrounding surface.

Driveway paving costs around $4,500 on average, but depending on many factors, you could pay anywhere from $2,500 to $6,600 or more. The size of your driveway will usually be the most significant factor, with more square footage increasing your costs. You can expect to pay between $2 and $15 per square foot for paving services. Some other factors that play a role include the following:

• Quality of the materials

• Contractor’s experience and expertise

• Site preparation and grading, if necessary

• Layout of your driveway

Your driveway contractor will probably recommend that you avoid driving on your new millings driveway for up to a week. Keeping pressure off the freshy applied millings will help the driveway to bind together. While the sun is helpful for binding millings, hotter weather can actually make the curing process take longer.
