Summer is prime time for parking lot resurfacing across Cincinnati, Northern Kentucky, and Southeast Indiana; a season when business owners and property managers look to repair winter damage, improve curb appeal, and prepare their lots for the year ahead. But high temperatures, intense humidity, fast-moving storms, and peak event traffic all combine to make summer paving uniquely demanding. For commercial property owners, choosing the right contractor isn’t optional; it’s essential. That’s why smart lot owners turn to Klekamp, the region’s trusted expert in asphalt paving, maintenance, and repair.
Heat & Humidity: How They Complicate Asphalt Curing
Asphalt gains its strength and flexibility through a process known as curing—cooling and hardening after compaction. But in Greater Cincinnati summers, pavement temperatures can exceed 130°F, complicating the curing process in several key ways:
- Overly rapid curing: When asphalt cools too fast due to surface heat, it may not achieve proper compaction. This results in weak bonds, surface raveling, or brittleness that leads to premature cracking.
- Delayed curing: On humid days, evaporation of the liquid asphalt binder slows, leaving the surface sticky, trackable, and more susceptible to deformation under weight.
- Oxidation: Intense summer sun can accelerate oxidation, hardening the asphalt surface prematurely and causing it to become brittle and crack unless it is protected by timely sealcoating.
To manage these challenges, Klekamp uses several strategies:
- Custom hot-mix asphalt blends formulated for high-temperature durability.
- Thermal monitoring tools that measure pavement and ambient temperatures in real time.
- Careful scheduling of asphalt delivery and placement to ensure compaction occurs during the optimal thermal window.
- On-site weather evaluation, which allows crews to adjust the timeline based on temperature, humidity, and wind conditions that affect curing behavior.
These proactive measures help Klekamp ensure every paving job is long-lasting, smooth, and ready to withstand the region’s seasonal extremes.
Urban Heat Zones: Thermal Load Matters
Parking lots in urban areas like downtown Cincinnati or river-adjacent industrial zones tend to retain heat longer, sometimes staying above 120°F well into the evening. Without proper compaction control and material choice, these surfaces are prone to soft spots, wheel ruts, and premature deformation. Klekamp uses thermal-resistant mixes and adjusts compaction timing to account for these retained heat loads.
Pop-Up Storms: Rain Is a Real Risk
In summer, storms can sweep through Greater Cincinnati with little warning. If rain hits freshly laid asphalt before it fully bonds, it can wash out binder, create surface blistering, or compromise adhesion. Klekamp crews are equipped to:
- Monitor live Doppler and radar forecasts.
- Install temporary protective covers.
- Halt and reschedule work if precipitation threatens the curing process.
Base Prep & Drainage: Curing Starts Below the Surface
Even perfect asphalt won’t last if the base isn’t properly prepared. Klekamp performs detailed patching, crack repair, milling, and laser-guided grading to ensure smooth drainage and a stable foundation. This groundwork prevents water accumulation that can compromise curing and cause subsurface damage—especially near the Ohio River or low-lying areas prone to pooling.
Precision Compaction & Grading
In hot weather, the compaction window narrows. Crews must work quickly and precisely to ensure the asphalt sets correctly. Klekamp’s professionals use:
- Temperature-calibrated rollers
- Nuclear density meters
- Laser-guided grade tools
These tools help ensure that the surface is compacted to exact specifications for slope and density—critical for long-term performance.
Crew Safety: A Top Priority During Summer
Summer paving involves working near 300°F asphalt in 90°F+ air temperatures. To protect workers, Klekamp enforces comprehensive safety protocols:
- OSHA-compliant signage and gear
- Frequent hydration breaks in shaded rest areas
- Rotating schedules to prevent overheating
- First-aid and CPR-trained supervisors on every job site
Safe crews mean efficient, focused work—and a better end result for your property.
