Aftercare for Your Asphalt Parking Lot

The day a crew finishes paving your parking lot, the surface looks perfect. What happens over the next few weeks has a lot to do with whether it still looks that way in a few years. Fresh asphalt is firm enough to handle traffic quickly, but it continues to cure and harden for some time. During that period it is more vulnerable to scuffing, dents and turning marks than it will ever be again.

For property managers, HOA boards and business owners, here is a practical aftercare plan.

The First 72 Hours

Keep vehicles off the new pavement for as long as your contractor recommends. In mild weather that is often a day or two for cars. In the heat of a New Jersey summer, when the asphalt stays warm well into the evening, it can be longer. Heavy trucks should wait longer still.

A few things that help during this window:

• Barricade entrances clearly with cones, tape or sawhorses, and post signs so tenants and customers know the timeline.
• Let deliveries know in advance so drivers do not roll a box truck onto soft pavement.
• Keep pedestrians to designated paths where possible. Heels and bike kickstands can leave marks in warm asphalt.

The First Season

Even after the lot opens, the surface is still curing. For the first several weeks, especially in hot weather:

Avoid turning wheels in place. Drivers who crank the steering wheel while parked can scuff and twist fresh asphalt. This is most noticeable in tight spaces near building entrances.

Watch heavy, concentrated loads. Dumpsters, storage containers, trailer tongue jacks and lifts put a lot of weight on a small footprint. Set them on plywood or steel plates to spread the load, or place them in a spot where a small depression will not matter.

Keep vehicles from parking in the same spot for days. A box truck or equipment trailer sitting in one place during a heat wave can leave dents.

Tell your landscape crew. Mower decks, trailer ramps and the blades of edgers can gouge the edge of a new lot. A quick word with them saves a lot of frustration.

Ongoing Care That Pays Off

Once the asphalt has fully cured, the focus shifts from protecting a soft surface to protecting the base underneath.

Keep Water Moving

Water is the enemy of every parking lot. Make sure catch basins and storm drains stay clear of leaves, litter and sediment. Check that roof drains and downspouts discharge into the drainage system or onto landscaping, not across the pavement. After a heavy rain, walk the lot and note anywhere puddles linger.

Clean Up Spills

Gasoline, motor oil, hydraulic fluid and antifreeze soften asphalt binder. Spots under parked delivery vans and near loading areas take the most abuse. Soak up spills with an absorbent like cat litter, sweep it up, then wash the area with mild detergent and water.

Sweep Regularly

Sand, grit and debris act like sandpaper under tires and hold moisture against the surface. A regular sweeping schedule also keeps catch basins from clogging.

Inspect Twice a Year

Walk the lot in early spring and again in fall. Look for edges breaking off, holes, sunken areas around drains and spots where the pavement is starting to break apart. Problems found early, especially drainage and edge issues, can be corrected before winter freeze-thaw cycles turn them into bigger ones.

Be Careful in Winter

Ask whoever plows your lot to keep blades slightly raised and to watch curbs and edges. Use ice melt in measured amounts and avoid piling plowed snow where meltwater will sit on the pavement for weeks.

When Aftercare Turns Into Repair

Good aftercare stretches the life of a lot, but it cannot fix a failed base. If you start seeing alligator cracking, widespread holes or areas that hold water, it is time for a closer look.
