Aggregate base must be placed in uniform lifts not exceeding 6 inches uncompacted thickness and compacted to a minimum 95% of Modified Proctor maximum dry density at optimum moisture content before applying asphalt or concrete.
Dense-graded aggregate contains a continuous mix of large stone down to fine stone dust particles, allowing it to interlock and compact into an impermeable, high-strength structural base. Open-graded aggregate contains uniform clean stone with no fines, creating void spaces for water drainage.
Loose aggregate delivered in a dump truck settles and compresses under vibratory rollers and traffic. A 6-inch loose layer compacts down to roughly 5 inches, so you must order 10% to 20% more loose volume to reach your target finished elevation.
One cubic yard of dense-graded road base (crusher run, #411, or ABC) weighs approximately 2,900 to 3,100 pounds (1.45 to 1.55 tons) when compacted at optimal moisture.
Small residential areas require a heavy-duty forward/reversible vibratory plate compactor (minimum 5,000 lbs centrifugal force). Large driveways, parking bays, and roads require a 3-ton to 5-ton tandem vibratory steel-drum roller.
Adheres to certified architectural formulas and standard AASHTO T 99 / T 180 Moisture-Density Relations of Soils commercial trade provisions.
Accurate material takeoff requires reconciling nominal plan dimensions with real-world physical packaging and volumetric compaction. This engine evaluates Fill Area Length, Fill Area Width, Target Fill Thickness, Compaction Factor, Aggregate Gradation against certified engineering multipliers.
\text{Compacted Tons} = \frac{\text{Length} \times \text{Width} \times (\text{Depth}/12)}{27} \times (1 + \frac{\text{Compaction}}{100}) \times \text{Density (tons/yd}^3\text{)}Equation Reference: ASTM C29 / AASHTO T 19 Bulk Unit Weight Mathematical Model. Calculated results provide both theoretical net volume and practical jobsite gross totals factoring standard shrinkage and trim cuts.
Measure length, width, depth, or gauge with calibrated trade tools. Confirm grade level and structural subbase.
Factor a 5% to 15% allowance depending on job complexity to prevent costly project shutdowns from mid-job shortages.
Round up to whole commercial packaging units (bags, rolls, panels) and compare raw material cost against regional trade rates.
Building departments across the United States reference municipal standard codes (including the International Residential Code IRC, National Electrical Code NFPA 70, American Concrete Institute ACI, and ASTM international specs). Designing below these minimum safety thresholds risks structural deflection, inspection failure, and permit revocation.
