Budgeting a Three-Year Asphalt Maintenance Plan for an Oshkosh Multi-Tenant Lot

September 22, 2026

Fall is when next year's numbers get locked in. A three-year plan turns scattered repair invoices into one calendar that covers every property on your list.

Start With an Inventory, Not a Quote

Most asphalt budgets start the wrong way around: something fails, a number gets requested, and the line item lands in whatever year the failure happened. A plan starts with a written inventory instead. List every paved surface you are responsible for, not just the parking field: drive aisles, stalls, the dumpster pad, the apron where the lot meets the street, and any curb cuts.

For each surface, record square footage, the year it was paved or last overlaid, and the date of the last sealcoat. Properties age at different rates even when they were paved the same season, because sun exposure, delivery-truck routes and drainage all differ lot to lot. A building in Oshkosh, one in Neenah and one in Menasha will almost never come due in the same year, and the inventory is what proves it.

Rate Each Lot Before Any Money Gets Assigned

PASER, the Pavement Surface Evaluation and Rating system published by the Wisconsin Transportation Information Center at the University of Wisconsin-Madison, rates asphalt from 1 to 10. It was written for public roads, but applying it to private lots gives every line in the budget a defensible reason to exist. The manual ties each rating to a maintenance response:

• 9 to 10, excellent: no maintenance required. Record the rating and move on.
• 8: little or no maintenance required.
• 7: routine crack sealing.
• 5 to 6: preservative treatments, which is where sealcoating belongs.
• 3 to 4: structural improvement and leveling, meaning overlay or recycling.
• 1, failed: total reconstruction.

Sequence Three Seasons Instead of Three Emergencies

With ratings in hand, the order almost writes itself. Year one takes the lowest-rated surfaces that can still be saved, plus any crack filling that is overdue. Cracks wider than a quarter inch are the ones that matter, because they carry water straight into the base, and water in the base is what freeze-thaw pulls apart every spring.

Year two picks up the middle of the list. Year three catches the lots sealed before the plan started, which come due again on a two to three year rotation. Crack filling always precedes sealing; sealer poured over an open crack hides a problem rather than closing it. Running one schedule across a portfolio is also how pavement maintenance for Oshkosh area properties stops competing with itself for the same few weeks of good weather, and it is the whole point of putting asphalt maintenance plans on a fixed rotation.

Build the Calendar Around a Five-Month Season

Sealer needs pavement and air at 50 degrees F and rising, sustained across a 24 hour period, with no rain for 24 to 48 hours after it goes down. Oshkosh normals for 1991 to 2020 put May at 67/48, June at 77/58, July at 81/63, August at 79/61 and September at 72/52 degrees F, while April sits at 55/37 and October at 58/40. That is roughly five dependable working months against seven months of frost, salt and thaw, which is laid out in more detail on the Oshkosh winter pavement data page.

Two scheduling notes apply to Oshkosh in particular. EAA AirVenture ran July 17 to 28 in 2025 and drew roughly 704,000 people to Wittman Regional Airport, so any lot on that side of town should be booked outside the late-July window. And crack filling does not need the same warmth sealer does, so it can move to the shoulder months, spring or fall, when cracks are open at their widest.

Know What Moves the Number, Not Just the Number

A three-year plan is easier to defend when the drivers behind each figure are written down next to it. Surface condition and prep work carry the most weight: crack filling, priming oil spots, and patching failed areas before anything is sealed. Edge work, property access and lot configuration matter too, since a lot with tight islands and constant traffic takes longer than an open rectangle of the same size.

After-hours or weekend scheduling to keep tenants operating, and where the job falls in the season, both shift the picture as well. A breakdown of those drivers lives on the cost page, and reading it before budget season is how a number stops looking arbitrary to an owner.

Put Striping and Compliance on the Same Line

Striping follows the sealer cure, usually the next day and sometimes the same evening on a small lot in warm, dry weather. Plan on a full day of cure before traffic returns either way, and tell tenants in advance rather than the morning of.

Accessible stalls and access aisles are governed by the 2010 ADA Standards for Accessible Design, and faded fire lanes and directional arrows are among the first things an inspector or insurer notices. Budgeting line striping as part of the same year as the sealcoat costs one mobilization; discovering it after a complaint costs two.
