How much aggregate base do I need?
Multiply the area in square feet by the compacted depth in inches, then divide by 324. The calculator currently adds a 10% planning allowance. A 60 by 12 foot driveway with 4 inches of base needs 8.89 cubic yards before that allowance, or 9.78 cubic yards with it. Ask the supplier to confirm the loose delivery quantity and any conversion to tons.
Which base and asphalt thickness should I enter?
Use the depths selected for your project. Vehicle loads, existing ground, drainage and the condition of retained material influence that choice. Entering a greater depth changes the calculated quantity; it does not establish the pavement design.
How do I measure a driveway that is not rectangular?
Divide the driveway into simple sections, measure each section and add their areas without overlap. Use Quantity for repeated areas with the same dimensions. Include parking pads or widened portions when they are part of the proposed work.
Can I calculate aggregate base without asphalt?
Yes. Set asphalt thickness to zero for a base-only calculation, or base thickness to zero for an asphalt-only calculation. Account for removal and preparation separately. An asphalt-only calculation does not confirm that the existing base can be retained.
What does the budget range include?
It reflects the dimensions, layer depths, access and preparation options you select. The current tool shows an initial range of 85% to 115% of its calculated total. Site conditions and the written scope determine the project price. An emailed calculation is a planning summary, so compare its assumptions with the project proposal.
Do I need permits for driveway work in Sacramento?
Check the authority for your address. Work in the City's public right of way may need an encroachment permit, and a new or widened driveway may need a driveway permit. Confirm the street connection and permit path before including that work in the project.
What should happen before excavation?
Premark the proposed excavation in white and contact USA North 811. Follow the ticket start time and confirm all required responses before digging. Private lines, such as irrigation or an owner-installed supply to an outbuilding, can require separate locating.
Do I have to give contact details to calculate?
The initial calculation uses the property address, ZIP code, measurements and scope options. Name, email and phone fields appear if you choose to continue after seeing the result. You can review the calculation before taking that next step.
