| Density and Load Factors | |
|
Whilst measured quantities are generally ‘in situ’ or ‘in place’ quantities, the actual quantity to be removed and/or spread and levelled is, in practical terms, the ‘loose’ volume. The following table indicates the approximate density (weight) and load factor of common materials. Approximate Density and Load Factor of Common Materials |
