The Bottom Line: For Southern Illinois, asphalt is usually the better choice due to our freeze-thaw cycles, lower upfront cost, and easier repairs. However, concrete may be preferable in specific situations.
Quick Comparison
| Factor | Asphalt | Concrete | Winner |
|---|---|---|---|
| Upfront Cost | $3-$7/sq ft | $5-$10/sq ft | Asphalt |
| Lifespan | 20-30 years | 30-40 years | Concrete |
| Freeze-Thaw | Flexible, handles well | Can crack | Asphalt |
| Repairs | Easy, affordable | Difficult, visible | Asphalt |
| Maintenance | Sealcoat every 2-3 yrs | Minimal | Concrete |
| Installation Time | 1-2 days | 3-7 days cure | Asphalt |
Why Asphalt is Better for Southern Illinois
1. Handles Freeze-Thaw Cycles
Southern Illinois experiences significant temperature swings. Asphalt's flexibility allows it to expand and contract without cracking. Concrete is rigid and more prone to cracking during freeze-thaw cycles.
2. Lower Upfront Cost
Asphalt costs 30-40% less than concrete to install. For a typical 600 sq ft driveway:
- Asphalt: $2,400-$4,200
- Concrete: $3,600-$6,000
3. Easier and Cheaper Repairs
Asphalt repairs blend seamlessly with the existing surface. Concrete repairs are always visible and often require replacing entire sections.
4. Faster Installation
Asphalt can be driven on within 24-48 hours. Concrete requires 7+ days to fully cure before use.
When Concrete Might Be Better
- Decorative applications: Stamped or colored finishes
- Heavy equipment: If you'll park heavy vehicles regularly
- Low maintenance preference: Don't want to sealcoat
- Longevity priority: Plan to stay 30+ years
Maintenance Comparison
Asphalt Maintenance
- Sealcoating every 2-3 years ($0.15-$0.30/sq ft)
- Crack filling as needed
- Clean oil spills promptly
Concrete Maintenance
- Seal every 2-5 years (optional)
- Pressure wash annually
- Address cracks immediately to prevent spreading
Our Recommendation
For most Southern Illinois homeowners, asphalt is the smart choice. The lower upfront cost, better performance in our climate, and easier repairs make it the practical option. The money you save on installation can fund years of maintenance while still coming out ahead.
