cost to seal asphalt driveway
In addition to the base and topcoat, there are other costs that go into installing an asphalt driveway. If this is a brand new driveway, not just a resurfacing, a person can expect to pay up to $2.50 per square foot for a gravel layer under the asphalt. If drains are needed, that costs more too, as does sealing. For a chip seal, for instance, a person can expect to pay about $3.50 per square foot.
