Road Construction Activities

  • Clearing & Grubbing

  • Excavation

  • Subgrade

  • GSB

  • WMM

  • Bituminous layers


Quantity Calculation Methods

1. Excavation

Formula:
Length × Width × Depth


2. Embankment

Volume = Area × Length


3. GSB Layer

Volume = Length × Width × Thickness


4. Bituminous Work

Weight = Area × Thickness × Density


Example Calculation

Length = 100m
Width = 10m
Thickness = 0.2m

Volume = 100 × 10 × 0.2 = 200 cum
