Asphalt Calculator Support

Pick a calculator, enter your dimensions, and the results update as you type. The hot mix calculator gives tons, cubic yards, truckloads and material cost; adjust density, waste factor, truck capacity and price per ton to match your job and supplier.

Check three settings first: the density (the 145 lb/ft3 default is typical hot mix; use the presets for binder course, millings, cold patch or gravel base), the depth (make sure it is compacted depth in the unit you intended), and the waste factor. A 10 percent waste factor adds 10 percent to the raw tonnage by design.

Each calculator has a Units switch at the top: imperial (feet and inches, US tons) or metric (meters and millimeters, tonnes). On the hot mix calculator the unit system is saved with each job.

Multi-section jobs, saved jobs and PDF estimate export are Premium features. PDFs are generated on your device and shared through the iOS share sheet, so you can text or email an estimate straight from the job site. Saved jobs live only on your device: deleting the app deletes your saved jobs, and there is no cloud backup or account to restore them from.

If you reinstall the app or switch devices, open the Premium screen (tap "Go Premium" on the home screen or in Settings, or tap any locked calculator) and tap "Restore Purchases" to bring back your Premium subscription or Lifetime unlock. Make sure you are signed in with the same Apple ID you purchased with.

Subscriptions are billed through Apple, not by us. Manage or cancel anytime in your Apple ID subscription settings: open the iOS Settings app, tap your name, tap Subscriptions, then select Asphalt Calculator.

Cancel at least 24 hours before the end of the current period to avoid the next charge. The weekly plan includes a 3-day free trial; cancelling during the trial means you are never charged. The Lifetime option is a one-time purchase with nothing to renew or cancel.

Refunds are handled by Apple under App Store policy: request one at reportaproblem.apple.com.

The calculators work offline and we collect no data: no account, no analytics, no ads, no tracking. Your saved jobs stay on your device. See the Privacy Policy.
