What surface is needed before asphalt — Renewable Energy Project
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.
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.
How to Grade Before Asphalt
Grading before asphalt should establish the correct supporting profile and allow for the specified surfacing thickness. Resolve drainage and transition errors before paving.
Before moving material
Confirm the supporting-layer acceptance and finished elevations.
Receiving operation and checks
Hand over to the asphalt contractor with level and acceptance records. Check joints, gutters and connections to existing pavement.
Asphalt placement should not be presented as a function of the scraper.

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.

Surveying existing ground is the first project-stage record of the surface to be changed. Agree the coverage before the survey so critical features are not omitted.
Before moving material
Define boundaries of work, reference control and required detail.
Receiving operation and checks
Issue the survey with datum, units and limitations stated. Check control-point agreement and representation of abrupt terrain changes.
A survey deliverable should not be confused with a legal boundary determination.
