005 Reinstatement of sub-base and road-base in non-bituminous materials

This unit is designed to allow the candidate to demonstrate the skills and knowledge required to reinstate sub-base and base (roadbase) in non-bituminous materials. The candidate will be able to prepare the subgrade to receive subsequent layers, to identify and select materials to be used for the reinstatement, and to reinstate the sub-base or base (roadbase) correctly, using the correct equipment. They will also be able to identify and dispose correctly and safely of surplus materials, and materials that cannot be re-used.
