Onsite Crushing & Screening
Turn concrete, asphalt, and rock into usable base—right on your site. Mobile crushing & screening that cuts haul-off, speeds schedules, and delivers the gradations your plan calls for.
Recycle materials at the source—and keep your project on schedule.
Davis & Sons brings mobile jaw/impact crushers, scalping screens, and stackers to your jobsite to process concrete, asphalt, and rock into usable aggregate. Onsite recycling reduces disposal and trucking costs and keeps material supply aligned with your earthwork sequencing.
What we crush & what you get
- Concrete: rebar-tolerant processing with magnets; outputs for base/subbase and backfill (e.g., ¾″ minus, #57/#67, pipe bedding). FHWA notes reclaimed concrete performs well in granular base.
- Asphalt: RAP for haul roads, temporary lifts, and blend stock. (Recycling reduces virgin demand and trucking.)
- Shot rock/brick: screened to common site gradations for pads and access.
For DOT work: TDOT allows RCA for base/subbase/shoulder with material controls; we coordinate with your engineer and testing plan as needed.
How we work
- Site walk & plan – volumes, feed material, target gradations, access/laydown.
- Set & sequence – crusher + screen train, dust suppression, utility locates. OSHA silica Table 1 methods (water spray/mist at crushers and transfer points) are standard.
- Produce & stack – stockpiles by size; daily tickets and yield tracking.
- Closeout – clean demob and final quantities for your records.
Why onsite pays off
- Lower hauling and tipping vs. offsite disposal; crushed material can be reused as base/fill or sold, depending on the job.
- Schedule control—make material as you grade; fewer plant/quarry dependencies.
- Sustainability—EPA recognizes C&D recycling reduces virgin extraction and disposal.
Safety & compliance
- Silica controls: water sprays/mists and housekeeping per 29 CFR 1926.1153; follow manufacturer procedures and Table-1 guidance for crushing machines.
- Quality use of RCA: FHWA provides guidance on RCA in base/subbase and concrete; we match the engineer’s spec and testing plan.
Typical use cases
- Site/demo recycling for pads and roadbeds
- Industrial redevelopments and plant work
- Road reconstruction & utility trenches (temp and permanent)
- Access roads, laydown yards, and backfill
Service area

FAQs
Can you meet specific gradations?
Yes—jaw/impact crusher with a matched screen lets us dial common sizes (#57/#67, ¾″ minus, RAP blends). Your engineer’s sieve spec governs acceptance.
Can recycled concrete be used under pavements?
FHWA documents widespread use of reclaimed concrete in granular base/subbase with good performance when processed correctly.
Is RCA allowed on TDOT projects?
TDOT permits Reclaimed Concrete Aggregate as base/subbase/shoulder with contamination limits and documentation. We coordinate submittals and testing as required.
Call to action
Ready to crush it onsite?
- Request a site review (material list, volumes, gradations, access).
- Get a production plan with estimated TPH, days on site, and stockpile layout.
- Ask dispatch about pairing hauling + screening to move and make material on the same schedule.
