#610 Stone (Dense-Graded Granite Base)

#610 Stone (Dense-Graded Granite Base) — The Engineered Sub-Base Contractors Spec by Name #610 Stone is the dense-graded crushed granite base that locks hardscape, driveways, and sub-grades down for decades. A continuous gradation from 1" down to dust — angular faces interlock, fines fill the voids, and the whole layer compacts essentially solid under a plate compactor. Meets Mass DOT M1.03.1 / AASHTO M147 dense-graded base spec. If the plan sheet says "610," "crusher run," or "dense graded aggregate," this is it. At a glance Spec name #610 Stone (Mass DOT M1.03.1 / AASHTO M147 dense-graded base) Material Crushed granite + granite fines, native to the Boston area Nominal size 1" to dust (continuous gradation, dense-graded) Composition Angular crushed granite with stone dust fines for tight compaction Weight ~2,800–3,000 lbs per cubic yard (~1.4–1.5 tons) Coverage 1 yd³ covers ~80 sq ft at 4" depth (compacted) Also known as 610, crusher run, ABC stone, dense grade aggregate (DGA), processed gravel, road base Sold by The cubic yard, bulk dump truck delivery What it's good for Compacted base under interlocking pavers, flagstone, and patio stone Retaining wall footings and segmental block wall foundations Driveway sub-base under finish gravel or asphalt Walkway and patio sub-base where settling can't be allowed Parking pad and shed pad construction Road base on private driveways and woods roads Gradation (Mass DOT M1.03.1 / AASHTO M147 typical band) Sieve size % passing 1" (25 mm) 100 ¾" (19 mm) 70 – 100 #4 (4.75 mm) 35 – 65 #40 (425 µm) 12 – 32 #200 (75 µm) 0 – 12 How much do I need? For a 200 sq ft paver patio with a 4" compacted base, plan on about 2.5 cubic yards. ICPI guidelines recommend 6" of dense-graded base for residential pedestrian use and 8"+ for vehicular — so a 600 sq ft driveway base at 8" runs about 14.8 yards. Always compact in 2–3" lifts with a plate compactor for proper density. How #610 compares to neighboring products #610 vs. #57 / #89: #610 is dense-graded (with fines, compacts). #57 and #89 are clean (drain). Use #610 where compaction matters; use #57 or #89 where drainage matters. #610 vs. crushed concrete: Crushed concrete is the recycled equivalent — lighter on the wallet, slightly lower bearing capacity. #610 is the virgin-aggregate spec. Residential equivalent: Same product family as our Dense Pack ¾" to minus — two ways to ask for the same material. Frequently asked questions What is #610 stone? A dense-graded crushed-stone base material with a continuous gradation from 1" down to dust. Designed to compact tight under load. The "6" refers to the top size band and the "10" to the bottom, in the unified stone-numbering convention. Is #610 the same as crusher run? Essentially yes. "Crusher run" is the colloquial name; "#610" or "dense-graded aggregate" is the spec name. Same product family, regional naming differences. How thick should a #610 paver base be? For pedestrian patios and walkways, 4–6" compacted in 2–3" lifts. For driveways and vehicular use, 6–8" compacted. Always compact each lift before adding the next. How much does a cubic yard of #610 stone weigh? About 2,800–3,000 lbs per cubic yard, or roughly 1.4–1.5 tons. Slightly heavier than clean #57 because of the fines.
