Martin Marietta’s #57 crushed stone is one of those materials you never notice, but you feel it under every fresh road surface and beneath countless driveways and foundations across the United States. Mid-sized, angular, grey-beige stones crunch underfoot, yet their job is all about stability, drainage and load-bearing strength.
Background on the Martin Marietta Materials stock
From aggregates like #57 crushed stone to cement and asphalt, Martin Marietta Materials is tightly linked to US infrastructure spending and construction cycles.
What #57 stone actually is
#57 crushed stone sits in the middle of the aggregate size spectrum, typically around 19 mm down to 9 mm, with angular edges from mechanical crushing rather than smooth, river-worn shapes. That geometry helps the particles lock together, creating a stable but well-draining base layer.
Martin Marietta produces #57 stone from hard rock such as granite, limestone or trap rock at its network of quarries across the US, then screens it to this standardized size range for consistent performance in mixes and base layers.
Where builders actually use it
On a construction site, #57 crushed stone appears everywhere once you start looking: under new asphalt roads, as the open-graded layer beneath concrete slabs, or as a drainage bed along foundations and retaining walls. Contractors value the way water passes through the voids while the angular stones stay firmly in place.
In ready-mix concrete, this size often serves as a primary coarse aggregate, balancing workability with strength, while in residential projects it ends up in driveways, walkways and as decorative yet functional ground cover around houses.
How it behaves on site
Spread a load of Martin Marietta’s #57 crushed stone and you notice how quickly it levels out under a rake, the pieces interlocking as a plate compactor hums over the surface. The layer feels firm under boots, with just enough give to bed in further under load.
Because the gradation is relatively uniform, the material does not pack into a dense, sealed mass. Instead, it stays free-draining, which helps prevent frost heave in colder regions and reduces standing water under pavements and slabs.
Advantages over other aggregate sizes
Compared with finer blends like crusher run or dense-graded base, #57 crushed stone offers better drainage, making it a natural choice for French drains, septic fields and behind-wall backfill where water management matters more than ultimate compaction.
Against larger riprap or #3 stone, #57 is easier to handle with small equipment and hand tools, fits better in confined formwork and creates a smoother bedding plane for pipes and concrete elements.
Logistics, supply and CO? angle
Aggregates are heavy and low value per ton, so distance from quarry to jobsite can make or break a project budget. Martin Marietta highlights its extensive regional network of quarries, rail connections and distribution yards to keep freight distances down for customers.
That logistics footprint also ties directly into embodied carbon: shorter hauls mean lower transport emissions, while consistent local supply reduces the risk of contractors switching to suboptimal materials under deadline pressure.
Pricing and availability for customers
Pricing for #57 crushed stone is typically quoted per ton or per cubic yard and varies strongly by region, distance and geology, with denser, hard rock products often commanding a premium in urban markets. Contractors usually negotiate delivered prices based on project volume and duration.
Martin Marietta sells #57 stone primarily to ready-mix producers, road builders, civil contractors and sitework companies across the US, with orders commonly scheduled just-in-time to match pour sequences and paving windows.
Where #57 stone reaches its limits
Despite its versatility, #57 crushed stone is not a universal answer. For heavily trafficked road bases that must be tightly locked and smooth, engineers may specify a dense-graded aggregate instead, which compacts into a more continuous matrix.
For purely decorative landscaping, some homeowners prefer rounded pea gravel that feels softer under bare feet and offers a different visual texture, accepting the trade-off of less interlock and more stone movement over time.
Company context and stock angle
Martin Marietta Materials, a major US supplier of aggregates, cement and asphalt, positions products like #57 crushed stone at the core of its aggregates-led portfolio aimed at infrastructure and non-residential construction. According to market data, shares of Martin Marietta Materials (US5732841060) last traded on the NYSE around the mid-600 US dollar range.
