What is Recycled Concrete Aggregate (RCA)?
Recycled Concrete Aggregate, commonly known as RCA, is a high-density crushed stone product manufactured from reclaimed concrete slabs, sidewalks, and curbing. At Spartan Aggregates, we process this material through industrial crushers and precision screens to produce a clean 1.5” minus aggregate—a well-graded mix ranging from 1.5-inch stone down to fine binder dust.
The "Self-Binding" Technical Advantage
RCA offers a unique structural benefit over natural stone: secondary hydration. Because recycled concrete contains residual cement particles, it undergoes a chemical reaction when compacted with moisture. This causes the material to “lock” together and harden over time, creating a semi-rigid base that is exceptionally resistant to New Jersey’s freeze-thaw cycles and heavy vehicle ruts.
Common Construction Applications in North Jersey
Stone size affects compaction, drainage, and structural support.
- Residential Driveway Bases: The ideal foundation for asphalt, pavers, or decorative gravel in areas like Lake Mohawk and Byram.
- Heavy-Duty Equipment Pads: Stable staging for sheds, pole barns, and commercial containers.
- Construction Tracking Pads: Creating firm entry points for machinery on muddy Sussex County jobsites.
- Road & Parking Lot Sub-base: A high-density, budget-friendly alternative to DGA (Dense Graded Aggregate).
- Utility Trench Backfill: Providing stable, non-shifting support for pipe and conduit installations.
Comparison: RCA vs. Virgin Crushed Stone
Feature | Recycled Concrete (RCA) | Natural DGA / Quarry Stone |
Primary Use | Sub-base, Pads, Driveways | Drainage, Septic, Decorative |
Compaction Strength | Superior (Self-binding edges) | High |
Cost Savings | Significant (Typically 20%–40% less) | Standard Market Rate |

Frequently Asked Questions
Yes. In most load-bearing applications, RCA is functionally stronger than natural stone. Its angular shape allows for tighter interlocking, and the residual cement dust acts as a natural binder that hardens into a dense, concrete-like slab under compaction.
For a 4-inch deep base, you generally need 1 ton of RCA per 80-90 square feet. Because recycled concrete compacts significantly, we recommend factoring in a “compaction factor” when calculating your final tonnage to reach the desired grade.
No. RCA is a “dense-graded” material designed for maximum stability, not high-flow drainage. If your project requires water to move quickly (like a French drain or septic field), we recommend our 3/4″ Clean Crushed Stone.
We provide prompt bulk delivery to all of Sussex County, including Andover, Franklin, Hopatcong, and Wantage, as well as neighboring towns in Morris and Passaic Counties.
