Prescott Asphalt recommends treating every driveway bid as a 15-20-year decision: ask exactly how the contractor will prepare the base, control drainage, choose the asphalt, and compact the finished surface. Confirm credentials, pricing, warranty terms, weather limits, and the schedule in writing before signing. Those answers reveal whether competing proposals describe the same work or merely quote different prices.
Ask for the contractor's active Arizona ROC license number, paving classification, bonding, liability coverage, and workers' compensation, then verify the license before work begins. Request photos of driveway projects completed within the last 12 months and references you can call instead of relying on a verbal quote.
Ask whether the existing base is stable enough to reuse or needs full excavation. The proposal should state the compaction standard-95% of standard Proctor density is the target in this guide-and explain whether 4-6 inches of compacted aggregate beneath 3-4 inches of asphalt fits the soil and expected traffic.
Ask which equipment and crew will be on site, who manages the project, and how weather delays are handled. Asphalt should not be placed on a wet base, when overnight temperatures approach 50°F, or during active precipitation; the contractor should also explain driveway access during curing.
A cutaway view should distinguish the prepared subgrade, compacted aggregate base, and finished asphalt rather than showing the black surface alone.
A grading view should make the drainage path clear and show water moving away from the garage and foundation instead of pooling on the pavement.
This image helps show asphalt being rolled on a dry, prepared base so the importance of equipment, temperature, and compaction is immediately visible.
Typical line items are $1-$2 per square foot for excavation, $1-$3 for old-driveway removal, $1-$2 for base material and compaction, and $2-$5 for asphalt labor and installation.
The bid should connect excavation depth, aggregate base, 95% standard Proctor compaction, asphalt thickness, expected traffic, and drainage into one site-specific pavement plan.
Spring and fall usually offer steadier paving conditions than the July-September monsoon window. The schedule should prohibit placement on a wet base and explain when vehicles may return.
Plan the first seal coat for 6-12 months after installation and resealing every 2-3 years. With correct thickness, compaction, drainage, and crack care, an asphalt driveway can typically last 20-25 years in this climate.
| Ask About | A Complete Answer Should Specify | Why It Matters |
|---|---|---|
| Credentials | Active Arizona ROC license, bonding, liability coverage, and workers' compensation | Lets you verify the contractor before work begins |
| Base preparation | Whether the old base stays, excavation depth, aggregate depth, and compaction target | Controls settlement and early cracking |
| Asphalt and drainage | Mix choice, finished thickness, edge treatment, and planned slope | Clarifies performance and water flow |
| Itemized price | Removal, excavation, base, paving labor, cleanup, and payment milestones | Makes competing bids comparable |
| Schedule | Crew, equipment, project contact, weather delays, and traffic restrictions | Sets realistic access expectations |
| Warranty and care | Written crack and settling coverage plus seal-coat timing | Defines responsibility after paving |
A complete proposal should separate removal or excavation, subgrade preparation, aggregate base, asphalt placement, edge restraint where needed, and cleanup. It should identify the asphalt choice, agreed depths, grading plan, equipment, crew expectations, and the project manager you will contact. Ask whether the City of Prescott Community Development Department requires a permit for the specific work. Payment terms should be tied to clear project milestones rather than an unexplained full payment before work begins. Finally, get workmanship, material, cracking, and settling coverage in writing, including exclusions and the recommended seal-coat schedule.
Prescott's decomposed-granite soils can require deeper excavation to reach stable subgrade, while granite-heavy ground can drain slowly and make careful grading especially important. Skipping a proper aggregate base can allow movement and cracking within the first year. At roughly 5,300 feet of elevation, freeze-thaw cycles and temperature swings favor a flexible, well-compacted asphalt surface; concrete may last longer but generally costs more and takes longer before use. Ask whether standard hot mix asphalt, recycled asphalt content, or a permeable paving option is appropriate for the lot, budget, and stormwater needs. No mix should be placed on wet base material, and rain during compaction can damage the finished mat.
Can the existing base stay? Only a site assessment can show whether it is stable, deep enough, and properly graded or whether full excavation is needed. How long will the work and curing take? Most residential projects run one to three days, followed by 24-48 hours before light vehicle traffic and up to 7 days for full curing. When should a new driveway be sealed? Wait 6-12 months for the first seal coat, then consider resealing every 2-3 years. How long should the pavement last? Adequate compaction, correct thickness, drainage, early crack repair, and routine sealing support the typical 20-25-year service life described in this guide.
Share the driveway's current surface, drainage concerns, expected traffic, and any access limits. A site assessment can turn those details into a written scope you can compare line by line before approving the work.
