July brings the peak of Ohio's summer heat, with temperatures frequently reaching the high 80s and occasionally exceeding 90°F. These high temperatures pose specific challenges to asphalt pavement, requiring careful monitoring and preventive care to maintain your investment.
Understanding Heat's Impact on Asphalt
High temperatures cause the asphalt binder to become more fluid, leading to pavement deformation and rutting. This softening effect occurs when asphalt reaches temperatures that reduce its structural integrity. Additionally, extreme heat accelerates the oxidation process of asphalt, making the surface more brittle over time despite the temporary softening.
Signs of Heat Damage
During July, monitor your asphalt for these heat-related issues:
- Rutting: Permanent depressions in wheel paths, especially in high-traffic areas
- Surface Softening: Areas that feel soft or pliable under pressure
- Increased Cracking: New cracks forming from thermal stress
- Oxidation: Accelerated fading or graying of the asphalt surface
- Deformation: Areas where the pavement has lost its shape
Preventive Measures During Heat
Take these steps to protect your asphalt during July's heat:
- Avoid applying concentrated pressure (like vehicle jacks) directly on the pavement during the hottest parts of the day
- Hose down extremely hot surfaces with cool water if temperatures become excessive
- Ensure proper drainage to prevent water from pooling and then heating
- Limit heavy vehicle traffic during peak heat hours when possible
- Maintain sealcoating, which provides some protection against heat and UV rays
Weekly Inspection Routine
During July, conduct weekly inspections to catch problems early:
- Check for new cracks forming on the pavement surface
- Monitor drainage after rain events
- Examine high-traffic areas for signs of wear or soft spots
- Look for areas where the sealcoat may have worn away
- Check for oil stains that need treatment
Managing Extreme Heat
On days when temperatures exceed 95°F, be extra vigilant. Pavement surface temperatures can reach 120°F or higher in direct sunlight, which is particularly challenging for newly applied sealcoating. If you're planning sealcoating work, consider scheduling for early morning hours when temperatures are lower.
UV Protection
July's intense sunlight also accelerates UV degradation. A properly maintained sealcoat provides essential UV protection. If your sealcoat is wearing thin or showing signs of deterioration, plan for resealing in fall when temperatures are more moderate.
Water Management
Proper drainage becomes even more critical in July, as summer thunderstorms can deliver significant rainfall. Ensure all drainage systems remain clear and functional. Standing water combined with heat can accelerate deterioration and create weak spots in the pavement.
