Key takeaways
- The biggest cost drivers are size, removal of old pavement, base condition, thickness and grading or drainage work.
- Larger jobs usually cost less per square foot than small ones.
- A cheap bid often means a thinner surface or a skipped base. Compare thickness and base depth, not just the total.
- Always check the contractor's license on the CSLB website.
The Main Cost Factors
1. Size of the area
Paving has fixed costs: mobilizing a crew, trucks, a paver and a roller. Those costs are spread over every square foot, so a large parking lot usually costs less per square foot than a small driveway.
2. Removing the old surface
Tearing out and hauling away old asphalt or concrete adds labor, equipment and dump fees. An overlay, a new layer over sound existing pavement, avoids most of that, but only works if the base underneath is still good.
3. Base and subgrade condition
The base is the compacted layer of aggregate under the asphalt. If it's soft, wet or failed, it has to be dug out and rebuilt. This is the step cheap contractors skip, and it's why their pavement fails early.
4. Asphalt thickness and traffic
A residential driveway needs less thickness than a lot that carries delivery trucks, trash trucks or semis. Heavier traffic means thicker asphalt and a deeper base, and more material.
5. Grading and drainage
If water ponds or the slope is wrong, the site needs re-grading, and sometimes drainage features like valley gutters, before paving. It adds cost now but prevents early failure.
6. Concrete work
Curbs, gutters, aprons, ADA ramps and valley gutters are separate items. Hiring one contractor for both concrete and asphalt avoids coordination problems.
7. Access and site logistics
Tight access, steep driveways, long distances from the street, or working around open businesses and residents (phasing, nights or weekends) all affect labor and time.
8. Permits and city requirements
Work in the public right-of-way, such as driveway approaches, usually needs a city permit. Some cities and HOAs also have specific material or inspection requirements.
9. Finishing work
Striping, ADA markings and signs, wheel stops and, later, sealcoating are usually priced separately.
10. Material prices
Asphalt is a petroleum product, so its price moves with oil prices. A quote is usually only good for a limited time.
How to Compare Paving Bids
Make sure every bid spells out the same things:
- Asphalt thickness after compaction
- Base depth and whether failed base will be removed and replaced
- Whether old pavement is removed or overlaid
- Grading and drainage work included
- Concrete, striping and cleanup included or excluded
- License number and proof of insurance
Watch Out for "Leftover Asphalt" Offers
Be cautious of anyone who knocks on your door saying they have leftover asphalt from a nearby job and can pave your driveway cheap, today, for cash. Licensed contractors give written estimates. Always verify a license on the CSLB website before hiring.
