Asphalt Millings Calculator — Recycled Asphalt (RAP)
Specialised calculator for recycled asphalt pavement (RAP) millings. Millings density is lower than fresh HMA — typically 120–130 lbs/ft³ (1,920–2,080 kg/m³).
Things to Watch With Millings
- Lower density: calculator defaults to 145 lbs/ft³ — reduce result by ~15% for millings.
- Higher compaction loss: millings may need a larger buffer (15–20%).
- Best uses: rural roads, temporary access, base layers, or low-traffic driveways.
RAP Pricing (US, 2026)
RAP typically costs $10–$40 per ton, vs $100–$200 for fresh HMA. AASHTO and most state DOTs allow 15–30% RAP in new HMA mixes, more in base courses.
