Student ProjectHi! I'm a student developer building Calculat in my spare time. I was tired of searching for basic math tools and having to click through 10 spammy popups, loan ads, and cookie trackers.

A recycled asphalt calculator determines the tonnage of Reclaimed Asphalt Pavement (RAP) for use as high-density subbases, farm roads, and eco-conscious construction. Asphalt is America's most recycled material, with over 100 million tons recycled annually.
\text{Tons} = \frac{\text{Sq Yds} \times \text{Depth (in)} \times 102}{2000} \times 1.05Uncompacted to semi-compacted RAP averages 102 lbs per square yard per inch of depth (~1.80 tons per cubic yard).
Scenario: Installing a 75 ft by 16 ft RV parking pad with 4 inches of recycled asphalt subbase.
Square footage: 75 × 16 = 1,200 sq ft (133.33 sq yds).
Weight: 133.33 sq yds × 4 in × 102 lbs = 54,400 lbs.
Tonnage: (54,400 ÷ 2000) × 1.05 = 28.56 tons.
Yes. According to the Federal Highway Administration (FHWA), over 99% of reclaimed asphalt pavement is put back to use in new roads, roadbeds, and shoulders—surpassing aluminum cans and paper.
Recycled asphalt is typically 40% to 60% cheaper than virgin crushed limestone or hot mix asphalt.
Yes. Most modern state DOT paving specifications permit 15% to 30% recycled asphalt (RAP) blended directly into new virgin hot mix asphalt.
Because compacted recycled asphalt forms a semi-solid petroleum-bound crust, it resists weed penetration far better than standard gravel.
Calculate crushed asphalt millings (RAP) tonnage, cubic yards, and compacted coverage for affordable rural driveways and parking pads.
Calculate asphalt paving tonnage, square yards, and tri-axle truckloads for driveways, roadways, and parking lots.
