ABC Stone Formula:
From: | To: |
ABC Stone (Aggregate Base Course) is a crushed rock material used as a base layer for many construction projects including roads, driveways, and building foundations. It's composed of crushed stone mixed with finer materials like sand.
The calculator uses the following formula:
Where:
Explanation: The formula first converts all measurements to yards (depth from inches to feet, then cubic feet to cubic yards), then multiplies by density to get weight in tons.
Details: Proper calculation ensures you order the correct amount of material - too little delays your project, while too much wastes money. ABC stone is typically sold by the ton, making accurate weight calculations essential.
Tips: Measure your project area carefully in feet. For depth, consider both the compacted and loose depth (ABC stone typically compacts about 20-30%). Standard density is 1.5 tons/cu yd unless your supplier specifies otherwise.
Q1: What's the difference between ABC stone and regular gravel?
A: ABC stone has a higher percentage of fine particles that help it compact into a more stable base compared to plain gravel.
Q2: How much does ABC stone typically cost?
A: Prices vary by region but typically range from $25-$50 per ton, with delivery fees often extra.
Q3: How deep should ABC stone be placed?
A: For driveways, 4-6 inches compacted is common. For heavy traffic areas, 8-12 inches may be needed.
Q4: Does moisture content affect the weight?
A: Yes, wet material weighs more. The density values used are for dry material - account for 5-10% more weight if material is wet.
Q5: Can I use this for other materials?
A: Yes, but you'll need to adjust the density value (e.g., 1.4 for crusher run, 1.2 for sand).
