When temperatures soar into the 90s and beyond here in Middle Tennessee, most of us retreat indoors to air conditioning. But what about the pavement under our feet? Nashville’s intense summer heat puts serious stress on driveways and parking lots, and not all paving materials handle the heat the same way.
At R&R Paving, we’ve been dealing with Nashville’s sweltering summers for over three decades, and we’ve learned a thing or two about how different materials perform when the mercury rises. Whether you’re considering a new driveway or wondering why your current pavement is showing signs of distress, understanding how heat affects your paving choices can save you money and headaches down the road.
Asphalt: The Heat-Sensitive Workhorse
Asphalt is Nashville’s most popular paving choice for good reason—it’s cost-effective, durable, and handles our freeze-thaw cycles well. However, asphalt has a complex relationship with heat.
What Happens in Extreme Heat
When temperatures climb above 85°F, asphalt begins to soften. You might notice:
- Tire impressions in parking areas or where cars sit for extended periods
- Rutting in high-traffic zones like driveway aprons
- Surface bleeding where the asphalt binder rises to the top
- Increased susceptibility to oil stains and spills
The Silver Lining
While asphalt softens in heat, it also becomes more flexible, which actually helps it resist cracking. The key is proper installation and maintenance.
Pro Tip: Avoid parking in the same spot repeatedly during heat waves, and try to keep heavy vehicles moving rather than letting them sit on hot asphalt for hours.
Concrete: The Heat Champion
Concrete handles Nashville’s summer heat like a champ. Its light color reflects heat rather than absorbing it, and its composition remains stable even when temperatures soar.
Heat Advantages
- Stays cool to the touch compared to dark asphalt
- Maintains structural integrity regardless of temperature
- Reflects heat rather than contributing to the urban heat island effect
- No softening or rutting concerns
The Trade-offs
While concrete excels in heat, it’s more susceptible to cracking from our occasional winter freeze-thaw cycles and costs significantly more upfront than asphalt.
Tar & Chip: The Natural Heat Manager
Our tar & chip surfaces offer a unique middle ground that many Nashville homeowners don’t fully appreciate for hot weather performance.
Heat Benefits
- Natural stone surface stays cooler than solid asphalt
- Excellent drainage prevents heat-related surface issues
- No rutting problems since the stone aggregate bears the load
- Maintenance-free performance even in extreme temperatures
The loose stone surface of tar & chip actually provides better heat dissipation than solid paving materials, making it an excellent choice for Nashville’s climate.
Nashville-Specific Heat Challenges
Our Middle Tennessee location presents some unique challenges:
Urban Heat Islands
Nashville’s downtown core and densely paved areas can be 5-10 degrees hotter than surrounding areas. If your property is in areas like The Gulch, downtown, or heavily developed suburbs, heat stress on pavement is amplified.
Humidity Factor
Our notorious humidity doesn’t just make us uncomfortable—it affects how pavement materials cure and perform. High humidity can slow asphalt curing and affect long-term durability.
Sudden Temperature Swings
Nashville weather can shift from a cool morning to blazing afternoon in hours. This rapid temperature change creates expansion and contraction stress that properly installed pavement must be designed to handle.
Smart Strategies for Hot Weather Paving
Timing Your Project
The best time for asphalt installation in Nashville is actually during our hot months—May through September. The heat helps the asphalt cure properly and creates a more durable surface. However, we typically work early morning hours during the hottest weeks to ensure optimal installation conditions.
Design Considerations
- Proper thickness for your expected traffic load
- Quality base preparation to prevent heat-related settling
- Appropriate mix design for Middle Tennessee’s climate
- Strategic drainage to handle summer storms
Maintenance in Hot Weather
- Sealcoating should be done in moderate temperatures (60-80°F)
- Crack sealing is most effective during cooler months
- Avoid heavy loads on extremely hot days when possible
Making the Right Choice for Your Property
When choosing paving materials for Nashville’s climate, consider:
Choose Asphalt if:
- Budget is a primary concern
- You need a proven, repairable surface
- The area sees moderate to heavy traffic
- You’re willing to do periodic maintenance
Choose Concrete if:
- Heat reflection and cooling are priorities
- You want minimal long-term maintenance
- Budget allows for higher upfront investment
- You prefer a lighter-colored surface
Choose Tar & Chip if:
- You want a natural, rustic appearance
- Budget consciousness meets durability needs
- The surface will see light to moderate traffic
- You prefer minimal maintenance requirements
The R&R Advantage in Hot Weather
With four generations of experience in Middle Tennessee, we’ve learned how to work with Nashville’s climate, not against it. Our team schedules installations for optimal weather conditions, uses proven mix designs for our local climate, and provides realistic expectations about how your pavement will perform through our hot summers.
We’ve also learned that proper installation matters more than the material choice alone. A well-installed asphalt driveway will outperform a poorly installed concrete one every time, regardless of temperature.
Stay Cool This Summer
Nashville’s heat doesn’t have to be hard on your pavement. With the right material choice, proper installation, and appropriate maintenance, your driveway or parking lot can handle whatever Music City’s summer throws at it.
