Asphalt Driveways near you

The sequence that produces a long-lived driveway is unglamorous and mostly happens before any asphalt arrives. The existing surface and unsuitable soil are excavated to a depth that leaves room for both the base and the pavement; the subgrade is graded to shed water and compacted; a crushed aggregate base is placed and compacted in layers rather than dumped in one lift; the grades are checked again; and only then is asphalt laid and rolled while it is still hot enough to compact properly. Skipping or thinning any of those steps produces a driveway that looks identical on the day it is finished and different within three winters.

Drainage is designed in at the same time. The surface has to carry water off rather than hold it, which means a consistent cross slope and no low points where puddles form, and it means thinking about where that water goes once it leaves the pavement, because a driveway that discharges toward the garage or the foundation has traded one problem for a worse one. Water that sits on asphalt works into the surface, and water that reaches the base softens the material the pavement depends on.

Edges are the third structural question, and the most commonly ignored. An asphalt driveway with unsupported edges crumbles from the outside in, because there is nothing holding the material laterally when a tire runs near the edge. Backfilling and compacting the shoulder to the level of the pavement, or building a supported edge, is cheap at the time and impossible to add later without cutting the driveway back.

Sealcoating is a surface treatment. It coats the existing asphalt, changes how it looks and slows surface weathering, and it adds no strength whatsoever. The principle is the same one the Federal Highway Administration describes for roadway surface treatments: seal coats are used to seal fine cracks in the underlying pavement surface and prevent water intrusion while maintaining or improving friction, and slurry seals, it states, do not provide any structural benefit to the pavement. A driveway that is cracking because its base is failing will crack straight back through a fresh sealer, usually within a season.

Resurfacing, sometimes sold as an overlay, adds a new layer of asphalt over the old one. It can restore a surface that has weathered or raveled, and it buys real years where the base is sound and the grades are still right. It cannot fix a base problem either: paving over a section that moves under load simply moves the crack upward, and overlays raise the surface, which has to be reconciled with the garage slab, the walks and the apron at the street.

Reconstruction takes it out and rebuilds it, base included. It is the answer when the failures are structural rather than cosmetic: alligator cracking across large areas, depressions that hold water, edges that have crumbled well into the driving surface, or a driveway that was built on inadequate base to begin with. The honest test is what a contractor says when you ask why the driveway failed. If the answer is that it needed sealing more often, ask someone else.

Sealer is where a routine driveway purchase acquires an environmental and health dimension. The U.S. Geological Survey describes coal-tar-based pavement sealcoat as a potent source of polycyclic aromatic hydrocarbon contamination in urban and suburban areas and a potential concern for human health and aquatic life, and notes that as coal-tar-based sealcoat ages it wears into small particles with high levels of PAHs that can be tracked into homes and incorporated into house dust.

Two states have legislated. Minnesota's legislature banned the sale and use of coal tar-based sealants in 2013, effective January 1, 2014, products the state notes were commonly applied to asphalt driveways, parking lots and some recreational trails, after research found that coal-tar sealants contributed 67 percent of total PAHs in 15 metro-area stormwater ponds. Washington passed a law in 2011 prohibiting the sale and application of coal tar pavement sealants in the state. Various cities elsewhere have adopted their own restrictions.

Wherever you live, the practical step is to ask what is in the product before it goes down, and to get the answer in writing on the quote rather than as a verbal assurance. It is also worth asking how often a driveway genuinely needs sealing, since over-sealing builds a thick, brittle film that cracks and peels on its own, and a sealer applied over a dirty or damp surface fails early no matter what it is made of.

The section of driveway between your property line and the street generally sits in the public right of way, and cities permit work there separately from anything you do on your own land. Raleigh requires permits from the city before construction begins for adding or replacing a residential driveway, along with a survey showing the proposed work and its dimensions prepared to the city's transportation standard details and street design manual, and requires contractors working in the right of way or within five feet of it to have a current performance bond and general liability insurance on file, with an owner exemption affidavit for homeowners acting as their own contractor.

New access points are regulated even more closely, because a driveway is a connection to the road network. Cities typically control where a curb cut may be located, how wide it may be, how far it must sit from an intersection and whether it may be added at all, and a widened driveway or a second curb cut usually needs its own approval rather than being treated as a repair.

Two habits save real money. Confirm with the city, in writing, what is permitted before a deposit is paid, since a paving crew stopped halfway is the most expensive outcome available. And if your project changes drainage, impervious area or the sidewalk grade, expect the stormwater or engineering side of the city to have its own say alongside the permit for the paving itself.

New asphalt stays soft for a while, and the first season is when most avoidable damage happens. Point loads are the enemy: motorcycle and trailer jack stands, bicycle kickstands, ladder feet and the corners of heavy dumpsters all press into a warm new surface and leave permanent dents. Turning the wheels of a parked car in place scuffs it, and parking in exactly the same spot every day in hot weather leaves shallow depressions. Ask your contractor how long to wait before parking on it and what to avoid, and ask when it may be sealed, since sealing too early traps material that still needs to cure.

After that, the maintenance that actually extends life is unglamorous: keep water out. Filling cracks before winter stops the freeze-thaw cycle that turns a crack into a pothole, keeping the edges backfilled preserves the lateral support the pavement depends on, and clearing the pavement so water runs off rather than standing keeps the base dry. Sealer is cosmetic and protective at the surface only, which the Federal Highway Administration's characterisation of surface treatments makes clear, so a sealing schedule is never a substitute for crack repair and drainage.

Winter deserves its own habit. A steel plow blade dropped on asphalt gouges it and catches on any raised edge, so skid shoes or a rubber-edged blade are worth specifying to whoever clears your snow, and de-icing chemicals and the slush they create should be kept off the shoulders where they kill the vegetation holding the edge together.

Paving quotes diverge mostly in what is buried. The variables are the area to be paved, how much existing material has to be removed and hauled away, the subgrade soil and whether unsuitable material must be dug out and replaced, the thickness of the aggregate base and the compacted thickness of the asphalt, the grading and drainage work required, edge treatment, access for a paver and rollers, whether a permit and right-of-way work at the apron are included, and whether the price covers a new build, a resurfacing over what is there, or just a sealer. Ask every bidder to state the base thickness and the compacted asphalt thickness in the quote, and most of the difference between the numbers explains itself.

LokalMatch is where the shortlist comes from. You describe the driveway once, including its approximate size, the surface that is there now, what is failing and whether you are after a repair, a resurfacing or a rebuild, and paving contractors working in your area receive that request. The ones interested contact you directly. Pros pay for the requests they receive and homeowners use LokalMatch free of charge. LokalMatch does not pave driveways, does not set prices and does not vet, rank or recommend any contractor, so checking licensing where your state requires it, insurance, the permit at the street and the written thicknesses stays with you.
