Dense Graded Aggregate (DGA) cost depends on material, delivery, and job scope. This article breaks down exact price ranges in USD, with low, average, and high figures by common buying scenarios. Readers will see typical per-ton and per-cubic-yard estimates, plus regional movements that affect the final quote.
Assumptions: Midwest labor rates, standard DGA with 1.5-inch to 2.0-inch nominal maximum size, standard delivery logistics, and normal access to the site.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (DGA base aggregate) | $12/ton | $22/ton | $40/ton | Purchased loose material; excludes delivery |
| Delivery | $8/ton | $15/ton | $30/ton | Distance and access impact |
| Installation/Labor | $6/ton | $12/ton | $22/ton | Compaction and spreading |
| Total Installed Price | $26/ton | $49/ton | $92/ton | Includes material, delivery, and labor |
| Per cubic yard (approx.) | $40-$60 | $60-$120 | $90-$180 | Assumes compacted base depth 4-6 inches |
Cost drivers for Dense Graded Aggregate in Base Construction
Material grade and size distribution directly shift per-ton pricing, with tighter particle ranges or pre-washed rock costing more. Assumptions: 1.5–2 inch DGA used as base in light-traffic sites.
Delivery distance and access strongly impact transport charges. Longer hauls raise the per-ton delivery rate, especially on rural routes or congested corridors.
Typical price breakdown by materials, labor, and delivery
What buyers usually see in quotes is a 3-part split: materials, delivery, and installation labor. The following table shows representative ranges per ton and per cubic yard installed.
| Component | Unit | Low | Average | High | Notes |
|---|---|---|---|---|---|
| Materials | per ton | $12 | $22 | $40 | Rock product; price varies by quarry |
| Delivery | per ton | $8 | $15 | $30 | Distance-based; fuel surcharges apply |
| Installation/Labor | per ton | $6 | $12 | $22 | Spreading and compaction |
| Total Installed | per ton | $26 | $49 | $92 | Sum of all components |
Regional price variation for DGA by market
Prices shift with regional demand, quarry availability, and labor rates. Coastal or urban markets tend to be higher than rural inland regions, with delivery surcharges common during peak construction seasons.
Unit prices: per ton versus per cubic yard installed
Contractors often quote per ton for material plus delivery, and per cubic yard for installed base thickness. Typical installed ranges assume 4–6 inches of compacted depth.
Per ton installed ranges commonly fall between $40 and $92, while per cubic yard installed often sits between $60 and $180, depending on depth and compaction effort.
Job scope impact: driveway pad versus full road base
Smaller projects like a residential driveway pad have lower fixed costs but similar per-ton material pricing. Large base courses for commercial drive aisles may trigger larger delivery fees and require more equipment time.
Assumptions: driveway footprint of 600–1,200 sq ft; road base for a 1,000–2,000 ft long section.
Site conditions that shift final quotes
Site grading, slope, and access constraints can add handling, disposal, or additional compaction passes. Poor access may require smaller delivery loads, raising lift frequency and overall labor time.
Span of the project and weather windows influence scheduling and can add temporary mobilization costs or rush fees if timelines compress.
Ways to reduce Dense Graded Aggregate costs without sacrificing quality
Focus on scope alignment, material choice, and delivery logistics to trim costs without lowering performance. Consider combining projects, selecting locally sourced DGA, and planning deliveries during non-peak hours.
Strategies: batch multiple small projects, select a locally sourced quarry, and coordinate back-to-back deliveries to minimize partial loads.
Add-ons and other price considerations for DGA projects
Permits, inspections, or haul-site restrictions can add cost. Include disposal of excess material, pre-purchase tests, and dust control measures when budgeting.
Example: a small permit or inspection fee could add $100–$500 depending on jurisdiction.
