| Type | Description |
|---|---|
BACKFILL

Fill behind retaining walls or other structures such as quays, behind abutments and bridges. |
COUNTERWEIGHT
|
Embankment built on the side of the main road structure to reduce the settlement of the road. |

NOTE Definition from PIARC: Upper layer of the natural ground upon which the pavement is constructed. |
SUBGRADEBED
|
Upper part of the soil, natural or constructed, that supports the loads transmitted by the overlying structure of a road, runway, or similar hard surface. |
