Step 1: Input Collection

Step 2: Unit Conversions

• Imperial:
  Thickness (ft) = 3 in12=0.25 ft123 in​=0.25 ft
  Volume (ft³) = $100\text{ ft}\times 10\text{ ft}\times 0.25\text{ ft}=250\text{ ft³}$
  Volume (yd³) = 25027=9.26 yd³27250​=9.26 yd³

• Metric:
  Volume (m³) = $30\text{ m}\times 5\text{ m}\times 0.15\text{ m}=22.5\text{ m³}$

Step 3: Compaction Adjustment

• Imperial:
  Adjusted Volume = $9.26\text{ yd³}\times 1.10=10.19\text{ yd³}$
  (or $250\text{ ft³}\times 1.10=275\text{ ft³}$)

• Metric:
  Adjusted Volume = $22.5\text{ m³}\times 1.10=24.75\text{ m³}$

Step 4: Weight Calculation

• Imperial:
  Weight (lb) = $10.19\text{ yd³}\times 27\text{ ft³/yd³}\times 150\text{ lb/ft³}=41,269.5\text{ lb}$
  Weight (tons) = 41,269.52000=20.63 tons200041,269.5​=20.63 tons

• Metric:
  Weight (kg) = $24.75\text{ m³}\times 2400\text{ kg/m³}=59,400\text{ kg}$
  Weight (tonnes) = 59,4001000=59.4 tonnes100059,400​=59.4 tonnes

Step 5: Cost Estimation

• Imperial:
  Cost = $20.63\text{ tons}\times \$120/\text{ton}=\$2,475.60$

• Metric:
  Cost = $59.4\text{ tonnes}\times \$150/\text{tonne}=\$8,910$

Key Formulas

1. Volume:
   $\text{Length}\times \text{Width}\times \text{Thickness}$

2. Compaction Adjustment:
   Raw Volume×(1+Compaction %100)Raw Volume×(1+100Compaction %​)

3. Weight:

   • Imperial: $\text{Adjusted Volume (yd³)}\times 27\times \text{Density (lb/ft³)}$

   • Metric: $\text{Adjusted Volume (m³)}\times \text{Density (kg/m³)}$

4. Cost:
   $\text{Weight}\times \text{Cost per Unit}$

Unit Conversion Factors

Validation Rules

1. All dimensions and costs must be positive numbers.

2. Thickness must be > 0 inches or meters.

3. Compaction factor defaults to 10% if not specified.

This calculator ensures accurate estimates for asphalt quantity, weight, and cost in both unit systems.
