How Asphalt Repair Calculator Works
Visual calculation flow
Repair Type Pothole/Crack/Patch
→ L × W × D Volume (cu in)
→ × Density Material weight
→ Purchase Qty bags/gallons
Cold Patch: L × W × D (inches) × count ÷ 1728 × 120 lb/ft³ Step 1: Select repair type: pothole, surface patch, crack sealing, or skin overlay.
Step 2: For potholes: enter dimensions in inches × count. For cracks: length (ft) × width × depth.
Step 3: Select material: cold patch bags, hot mix (tons), or crack sealant (gallons).
Step 4: Get purchase quantity in bags/tons/gallons with repair tips included.
Asphalt Repair Calculator FAQs
How much cold patch do I need for a pothole?
One 50-lb bag of cold patch fills approximately 0.5 cubic feet—roughly a 12"×12"×6" hole. For a typical 8"×8"×4" pothole, you need about 1/4 bag. A 60-lb bag fills slightly more. Always buy extra; cold patch stores well in sealed bags and multiple thin layers compact better than one thick layer.
What's the difference between cold patch and hot mix for repairs?
Cold patch: Ready-to-use, available at hardware stores, works in any weather, good for DIY temporary repairs, lasts 1-3 years. Hot mix: Must be applied hot (300°F+), requires professional equipment, creates permanent bond with existing asphalt, lasts 15+ years. Cold patch is best for emergencies; hot mix for lasting repairs.
How much crack sealant do I need?
One gallon of rubberized crack sealant fills approximately 150-200 linear feet of 1/4" wide cracks (or 50-75 feet of 1/2" cracks). A 5-gallon bucket handles most residential driveways. Professional hot-pour sealant covers more at 250+ linear feet per gallon. Always clean and dry cracks before applying.
When should I repair vs replace asphalt?
Repair when: damage is localized, base is still solid, cracking is minor (under 25% of surface), and asphalt is under 15 years old. Replace when: alligator cracking is widespread, base has failed (soft/pumping), drainage issues exist, or repairs exceed 30% of replacement cost. An overlay (1.5-2" new asphalt) is a middle option.
