Regrade existing road base back to spec — without digging it out.
When base goes out of spec, the default is to excavate it, haul it off, and truck in new aggregate. CrushRite reclaims the base you already have — rip it, crush the oversize, screen out the contaminating fines, and re-lay it to a clean gradation. The material never leaves the road.
Why good base goes out of spec.
Aggregate base doesn't fail all at once — it drifts off the gradation curve. By the time the road shows it, the base is still mostly good material that's simply out of spec. That's reclaimable.
- ▸ Fines work up and contaminate the gradation, killing drainage and compaction.
- ▸ Oversize and broken-down material mix in until the base no longer meets the curve.
- ▸ Rutting, washboarding, and potholing from base that's lost its structural gradation.
- ▸ Grader and plow passes blend base into subgrade and haul good material off the crown.
The cost isn't the crushing. It's the trucking.
On a remove-and-replace, the excavation, disposal, and imported aggregate usually cost more than the base ever did. Re-screening reuses the material already in place — so most of that spend never happens.
- ▸ No excavation and disposal of the existing base
- ▸ No haul trucks running spoil off-site
- ▸ No imported aggregate trucked back in
- ▸ No landfill or tipping fees on the old material
- ▸ Shorter closures — the road rebuilds where it sits
One crew, one mobilization, base back to spec.
The same closed-circuit crusher-and-screen setup that produces new base reclaims existing base in place — fed by a ripper-equipped excavator instead of a quarry face.
Assess and sample
Walk the road, pull samples, and confirm the target gradation — CDOT Class 6, a custom curve, or the engineer's spec.
Rip and scarify
The ripper-equipped Cat 328D LCR breaks up the existing base and lifts it for processing — no separate dig-out crew.
Equipment specs →Crush the oversize
The Kleemann MR110Zi impact crusher reduces oversize and broken material back into usable fraction.
Equipment specs →Re-screen to spec
The MS19Z double-deck screen pulls the contaminating fines and reclaims a clean, on-spec base gradation in a single pass.
Equipment specs →Re-lay and verify
Reclaimed base goes back down to grade. Gradation sample reports available on the production run when the spec requires them.
Reclaimed base, held to the gradation you specify.
Reclaimed base is run to a target gradation, not just loosened and regraded — commonly CDOT Class 6 to Section 703 / AASHTO M147, or the custom curve your engineer of record requires. Closed-circuit operation holds the gradation across the production run, and sample gradation reports are available when the spec calls for them.
