The case for gravel
Gravel is the least expensive surface to install and works well on long, flat, low-traffic drives. It drains through, it's easy to patch, and it fits a rural look. The catch is that gravel is never finished: rock migrates into the yard, ruts and washboarding form, plows push it into piles, and every few years you're buying and spreading more. On slopes, monsoon runoff carries it away.
The case for asphalt
Asphalt costs more upfront but stays put. It sheds water, plows cleanly, doesn't track into the house, and stops the dust that blows across every gravel drive in the spring wind. A properly built and maintained asphalt driveway commonly lasts 20 years or more, and it adds curb appeal and resale value. On grades, it's often the only surface that won't wash out.
The in-between options
Recycled millings are firmer and less dusty than gravel at a modest price. Chip seal seals the surface completely and plows well, at less than hot-mix. Both are excellent for long rural drives.
What we usually recommend
- Short to medium driveways: asphalt. The cost difference over a small area is modest, and the maintenance savings add up.
- Long rural drives: asphalt at the house and parking area, chip seal or millings on the long run.
- Steep driveways: asphalt on the slopes, whatever you choose elsewhere.
- Tight budget now, pave later: compacted millings over a good base — they make a solid foundation for future asphalt.
Whatever the surface, the base and drainage underneath matter most. See typical prices in our cost guide.
Frequently asked questions
Does asphalt get too hot for a New Mexico driveway?
No. Well-compacted asphalt performs well in New Mexico summers. Just avoid parking trailer jacks or turning tires in place on it during its first few hot weeks.
Can I pave over my existing gravel driveway?
Often, after the gravel is regraded, supplemented and compacted into a proper base. Paving directly over loose gravel leads to early cracking.
Which surface adds the most home value?
Asphalt typically gives the strongest curb appeal of the options here, and buyers tend to view a paved driveway as one less project to deal with.
