Quarry process stone, commonly sold as dense graded aggregate or QP, is priced by ton or by cubic yard depending on supplier and local transport. This article breaks down typical price ranges, regional variations, and what drives the total cost for driveway base, paths, or drainage projects. Price factors include material quality, delivery distance, and whether the stone is sold by the ton or by cubic yard.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Material price (QP/DGA) | $8 | $28 | $70 | Per ton, regional variance |
| Delivery fee | $45 | $95 | $300 | Based on distance and load size |
| Installation labor | $0 | $1.50 | $3.50 | Per square foot for base prep and compaction |
| Site prep (grading, base) | $0 | $0.80 | $2.00 | Per sq ft |
| Taxes/ permits | $0 | $5 | $20 | Regional rules apply |
Assumptions: Midwest-to-Southern labor rates, standard 2A Modified asphalt- or gravel-type base, typical residential driveway scale, standard moisture content.
What Buyers Usually Pay For Quarry Process Stone
Typical total price ranges from $1,200 to $4,800 per project, depending on driveway length and base depth. The price per ton commonly falls between $12 and $50, with a regional average near $28-$40 per ton for standard QP. For smaller paths or walkways, homeowners might see per-yard charges in the $25-$60 range when buying by the cubic yard. Assumptions: standard vehicle access, no heavy excavation, and typical compaction in the base layer.
Price Components That Create the Quote
Quarry process stone quotes break down into six key parts. Understanding each helps compare bids accurately. A typical breakdown includes material, delivery, site preparation, labor to spread and compact, disposal if needed, and any overhead or permits.
| Cost Component | What It Covers | Typical Range | Unit |
|---|---|---|---|
| Materials | QP/DGA stone itself | $8-$70 | per ton |
| Delivery | Transportation from quarry to site | $45-$300 | per delivery |
| Labor | Spread, level, and compact the base | $0.50-$3.50 | per sq ft |
| Site prep | Grading, drainage work, sub-base preparation | $0.50-$2.00 | per sq ft |
| Taxes/Permits | Sales taxes or local permits if required | $0-$20 | per project |
| Disposal/Return trips | Uneven spoil or unused material disposal | $0-$50 | per load |
What Changes The Final Quarry Process Stone Quote
Two main variables often shift the quote: distance and base depth. Delivery distance can add $1-$2 per mile per ton, while base depth of 4-6 inches doubles material needs. Local supplier competition and seasonal demand can also nudge the price by 5-15%.
Regional Variations You Should Expect
Prices reflect regional supply chains. Coastal metro areas typically face higher delivery fees and material costs than inland markets. In the Northeast, expect higher ranges for both material and transport, while the Midwest may offer more favorable per-ton pricing with similar base preparation requirements.
Cost Scenarios by Driveway Size and Base Depth
For a standard residential driveway, base depth commonly ranges 4-6 inches. A 20×50 ft driveway with 6 inches of compacted QP often lands in the $3,500-$7,500 range, including delivery and labor. A shallower, 4-inch base may drop to $2,500-$5,000, depending on access and compaction requirements.
Per-Unit Pricing Details You Can Use in Quotes
When suppliers quote per unit, common units are tons and cubic yards. Per-ton pricing tends to dominate larger jobs; per-yard pricing suits smaller paths or edging projects. Example: 60 tons of QP for a 4-inch-thick driveway base could be $1,000-$3,000 in material alone, with delivery and labor doubling that in many regions.
Delivery Logistics and Access Impacts Cost
Access issues matter. Uneven terrain, steep driveways, or gated entries can raise delivery fees or require smaller loads and more trips. In urban areas, gate restrictions or restricted truck access may add surcharge or require offloading on the curb, increasing total time and cost.
Repair, Replacement, or New Installation: Price Implications
Decisions about reuse of existing material or starting fresh affect pricing. Replacing an old gravel base with fresh QP typically costs more upfront but improves drainage and compaction. For expansions or new sections, calculate material plus mobilization for a cohesive base.
How to Compare Quotes Without Getting Surprised
To compare bids fairly, align on: (1) material type and gradation, (2) delivered tonnage or yardage, (3) assumed base depth, (4) compaction method, and (5) any site prep or disposal. Ask for a line-item quote with a per-ton price, a delivery fee, and a per-square-foot labor rate.
Add-Ons and Alternatives That Can Change Total Cost
Consider alternatives or add-ons carefully. Option A: use QP for the driveway base only, option B: extend QP to edging and drainage, option C: replace with a different aggregate with different compaction requirements. Each choice affects material needs and labor time, shifting overall cost.
Real-World Quote Snapshot: Typical Project Specs
For a 40×10 ft path with a 4-inch base, one qualified quote might show 40 tons of QP, delivery, and labor totaling about $2,500-$4,000. Another bid with 60 tons and stricter compaction could run $4,000-$6,500. These examples illustrate how scope, distance, and compaction standards drive the price.
