A new asphalt driveway is one of the better investments a Gresham homeowner can make — done right, it adds curb appeal, handles the area's wet winters, and lasts decades. Done wrong, it cracks within a couple of seasons. The difference almost always comes down to what happens below the surface, and that matters more here than in many parts of Oregon because of east Multnomah County's clay soils and freeze-thaw exposure near the Columbia Gorge.
This guide walks through how a new driveway gets installed in Gresham, from the first excavation pass to the day you can finally park on it. For the broader statewide version of this process, see our step-by-step asphalt driveway installation process guide.
The crew measures the area, checks the grade, and plans drainage. In Gresham, this step pays special attention to slope — neighborhoods near the buttes and toward the foothills often have grade that needs to direct water away from the garage and the road. The driveway edges, width, and any turnaround or parking pad get marked out here.
The existing surface and topsoil are removed down to a stable subgrade, typically 8 to 12 inches depending on soil. Gresham's silt and clay loam drains slowly, so the crew grades to shed water and may over-excavate soft spots. This is where a careful contractor earns their fee — getting the subgrade right is the foundation of everything above it.
Crushed aggregate base rock is laid and compacted in lifts. In wet, clay-heavy soils, a deeper base and sometimes a geotextile fabric between the subgrade and rock prevent the fine clay from pumping up into the base over time. Proper compaction at this stage is what keeps the asphalt from cracking through its first winters.
Hot-mix asphalt is delivered and spread, usually in a binder course topped by a finer surface course, for a total of 2 to 3 inches of compacted asphalt on a residential driveway. The mix has to stay hot enough to compact properly, which is why Gresham paving happens in the warmer, drier months.
A roller compacts the asphalt to remove air voids and lock in density. Edges are shaped and supported — important on Gresham lots where soft shoulder soil can let unsupported edges crumble. Hand work finishes the transitions to the garage apron and any walkways.
Fresh asphalt looks ready long before it is. It needs time to cool and cure before heavy use, and it stays soft in warm weather for weeks. Most contractors advise waiting a few days before driving on it and longer before parking heavy vehicles or turning sharp.
Where your driveway meets a public street — the approach or apron — is usually regulated by the City of Gresham or, for some county-maintained roads, by Multnomah County. A new approach or a change to an existing one typically requires a permit and has to meet sight-distance and drainage standards. A contractor who works in Gresham regularly will know which jurisdiction applies to your street and handle the approach to code. Skipping this step can mean a stop-work order or having to redo the connection.
It is worth repeating because it is the single biggest factor in how long your driveway lasts. Gresham's position between the Gorge and the Cascade foothills means colder winters and more freeze-thaw cycling than inner Portland. Water that gets into a weak base freezes, expands, and breaks the asphalt from below.
A properly built driveway here uses:
Spending on the base is not an upsell; it is the part of the job you cannot see but absolutely feel ten years later.
A new driveway should not be sealcoated immediately — the asphalt needs months to cure first. After that initial period, regular maintenance keeps water out and the surface flexible. Our asphalt driveway maintenance services cover the sealcoating and crack repair that protect a new Gresham driveway through the wet seasons.
