Asphalt Parking Lot Calculator
Estimate hot mix asphalt for commercial parking lots — including two-lift designs with binder and surface course. For property managers, GC estimators and paving contractors.
Parking Lot Thickness Standards
- Light-duty (auto): 2 in binder + 1.5 in surface = 3.5 in over 6 in base.
- Standard: 2 + 2 = 4 in over 6–8 in base.
- Heavy-duty: 3 + 2 = 5–6 in over 8 in base.
