Frequently Asked Questions
How much does recycled asphalt cost?
Recycled asphalt (RAP) typically costs $7-$15 per ton, compared to $40-$80 per ton for virgin asphalt. This represents a 50-80% savings. For driveway projects, recycled asphalt millings cost $2-$5 per square yard installed, versus $5-$10 for new asphalt.
Is recycled asphalt as good as new asphalt?
Recycled asphalt performs well for driveways, parking lots, and rural roads. Modern RAP mixes with 20-30% recycled content perform similarly to virgin asphalt. Higher percentages (50%+) work best for base courses or when stabilized with emulsion or virgin binder.
How much can I save using recycled asphalt?
Savings typically range from 30-70% compared to virgin asphalt. A 1,000 sq ft driveway with 3 inches of asphalt costs $1,500-$3,000 with virgin material versus $500-$1,200 with recycled asphalt. Larger projects save even more due to economies of scale.
What is RAP content in asphalt?
RAP (Reclaimed Asphalt Pavement) content varies by application: Base courses: up to 50%, Binder courses: 20-40%, Surface courses: 10-25%, Driveways: 30-50%. Higher RAP content reduces cost but may affect performance in high-stress areas.
How many square feet does a ton of recycled asphalt cover?
One ton of recycled asphalt covers approximately: 80-100 sq ft at 2 inches thick, 55-70 sq ft at 3 inches, 40-50 sq ft at 4 inches. Coverage depends on density (typically 140-150 lb/ft³) and compaction.
What are the environmental benefits of recycled asphalt?
Recycled asphalt saves millions of tons from landfills, reduces mining of virgin aggregates, cuts energy use by 20-40%, lowers emissions, and preserves natural resources. Using 30% RAP reduces carbon footprint by approximately 25% compared to virgin mixes.
Do I need stabilizer for recycled asphalt?
For high RAP percentages (50%+), adding emulsion or virgin binder improves durability and cohesion. For driveways and low-traffic areas, 30-40% RAP often works without stabilizer. Cold recycling typically uses 2-4% emulsion or foamed bitumen.
How long does recycled asphalt last?
Properly installed recycled asphalt driveways last 10-20 years with maintenance. High RAP content (50%+) in base courses performs similarly to virgin material. Surface courses with 15-25% RAP have comparable longevity to conventional asphalt.
