Pre-Hot-Mix Grading
Describe the application, material route, growing or working area and proposed rental period. A listed scenario is not a claim that a Dugong rental unit or local service is available.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
Pre-Hot-Mix Grading
Pre-hot-mix grading prepares the layer beneath asphalt. Asphalt should not be expected to cure broad formation errors or drainage reversals.
Before moving material
Confirm the accepted layer, finished road profile and surfacing allowance.
Receiving operation and checks
Complete compaction and inspection before asphalt placement. Check transitions at joints, gutters and existing pavement.
Dugong can help prepare suitable ground; it is not an asphalt paver or compactor.

Pre-paving grading sets the profile below the finished paving system. Its target must allow for the planned bedding and paving thickness rather than equal the finished top level.
Before moving material
Confirm thresholds, finished surface levels and layer thicknesses.
Receiving operation and checks
Complete compaction and place the specified bedding and paving system. Check the difference between formation level and finished level.
Paving details and tolerances must come from the project specification.

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.
