Recycled Asphalt vs River Rock: Size, Cost, and Which to Use
Recycled Asphalt runs about $15 per ton and River Rock about $40 per ton. Compare size, drainage, compaction, and which one to use.
Overview
Recycled asphalt is made from reclaimed asphalt pavement that has been crushed and screened. When compacted, it hardens over time as residual asphalt binder reactivates, creating a durable and cost-effective driving surface.
River rock is naturally rounded stone from river beds and glacial gravel deposits, washed and screened into size bands from 3/4 inch to 8 inches. It costs $40 to $100 per ton in 2026, weighs 1.35 to 1.6 tons per cubic yard, and is the go-to decorative stone for dry creek beds, garden beds, borders, and drainage swales where the rock needs to look good and stay put. It costs two to three times what crushed stone costs because it is sorted and washed, and because the supply is limited to places with river gravel.
