Which machine should prepare ground before road base — Industrial Development
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.

How to Prepare Subgrade for Road Base
Before road base is placed, the subgrade should be accepted for both level and condition. An uneven or weak supporting surface can lead to thickness variation and premature failure above it.
Before moving material
Confirm formation level and identify unaccepted areas.
Receiving operation and checks
Inspect and accept before spreading base aggregate. Record level and material checks for the same work area.
Adding more base material is not automatically a remedy for weak subgrade.

The machine before Dugong determines what material arrives; the machine after Dugong determines what surface must leave. An excavator can expose formation, a loader can deliver a stockpile, and a roller can compact the placed layer. The scraper's role is bounded by those interfaces.
Before moving material
Identify the upstream operation and its remaining defects.
Receiving operation and checks
Hand over the measured surface to compaction, cultivation, paving or turf preparation. Record which operation owns levels, materials and final acceptance.
The workflow can include Dugong where suitable; it does not assume Dugong replaces adjacent equipment.

Preparing ground for a roller means placing a suitable layer that can be compacted consistently. Correcting levels is only one part of that preparation.
Before moving material
Confirm the compaction brief and accepted supporting surface.
Receiving operation and checks
Roll, inspect and test the layer using the chosen method. Check areas near edges and structures that the main roller cannot reach.
Do not use an attractive finish or scraper tyre marks as compaction evidence.
