New asphalt typically needs 24 to 72 hours to dry before it can handle light foot traffic and careful driving. Although it may appear solid after a few days, the full curing process, where the asphalt reaches its peak strength, takes much longer—generally from 30 days to a year.

During this extended curing time, the surface remains relatively soft and can be damaged by heavy vehicles, sharp objects, or high temperatures. To protect your investment, it's best to avoid parking heavy machinery on the asphalt until it has fully cured.

The exact time required for drying and curing depends on several factors, including the weather, the specific asphalt mix, and its thickness. For the most accurate advice tailored to your situation, consult with your asphalt contractor.

The average cost to repair an asphalt driveway is around $2,459 to $2,500. However, prices can range from $100 for minor DIY crack filling to over $4,000 for more extensive professional work. Costs are often calculated per foot, with minor repairs costing $1 to $3 per linear foot and heavier damage like potholes, sinking, or crumbling costing $2 to $5 per linear foot. Patching smaller potholes can cost around $2 to $3 per square foot. The final price depends on the severity and extent of the damage, driveway design, local contractor rates, and whether sealing is included. For major repairs, it is recommended to hire a professional, and you may get a better deal by bundling repair and sealing services together.

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.

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.
